The unique material of the model makes it almost visually indistinguishable from a real vertebral column. The flexible vertebral column including occipital plate, pelvis and sacrococcyx is mounted on a stand. Within the spinal canal, the spinal cord with cauda equina and exiting nerve roots are represented in flexible material. This model is particularly useful in studying the phases of bone growth. This includes: • Vertebrae - partially incomplete development of vertebral bodies and vertebral arches. • Sacrum – as yet incomplete fusion of individual sacral vertebrae. This commences at around the age of 15. • Pelvis – still open Y cartilage as main growth plate of the acetabulum. The hip, pubic and ischial bone parts are not yet connected (didactically fixed with brackets in the model). These fuse around the age of 14-16. BS-A52.....$238

(6-part bony skull) … “has an “aged” look that makes it appear like a real specimen. All the teeth are present and fine structures like the styloid process, sphenoidal spine, and pterygoid hamulus are all pristine. These fragile structures usually break shortly after students get their hands on a skull. However, in their plastic state they are stronger and likely to withstand the rigors of use better than the original. This is also true of thin areas such as the lamina papyracea and other parts of the orbital wall, which, though recognizable on the model, are unlikely to break as readily as a natural specimen would. One could say that the model has gained strength and durability at, perhaps, some small trade-off with realism, but this exchange is well worth making for primarily a teaching tool.” -David Rapaport, Ph.D., Division of Anatomy, Department of Surgery, University of California, San Diego

Anatomy | Anthropological Skulls

Bone.Clones®.Hominid.SeriesEach hominid was carefully researched and re-created based on casts made from the original fossils, the latest literature and full color, life-size photographs, or some combination thereof. Every effort has been made to accurately re-create anatomical details of color, size, shape, reconstructed areas, and bone/fossil texture, however, they are not intended for research purposes. The hominids offered in this series are high-quality recreations that can be advantageously used by educators as important visual aids in the classroom, and appreciated by the general public.

Osteological ReproductionsA..Australopithecus boisei.SkullThis important find by R. Leakey at Koobi Fora, Kenya in 1969 helped to shed light on the controversial hypothesis that all australopethicines were of the same species, and tended to support the classification of boisei as a separate species of Australopithecus. The cranium is virtually complete, with a brain volume of 510cc. Carefully researched, every effort has been made to re-create anatomical details of color, size, shape, reconstructed areas and bone/fossil texture.BS-W59306...$195

B..Homo neanderthalensis.Skull.Discovered in 1908 in La Chapelle-aux-Saints, France it was the most complete Neanderthal skull found at the time. Called the "old man" it is clear that he lived a long time, having identifiable pathologies, such as the declined tooth sockets in the molar region. Despite his very large brain capacity (over 1,600 cc) early descriptions declared him to be primitive. More recently, however, many consider Neanderthal as a highly successful and social species. This cranium is representative of many fossil remains of neanderthals found throughout present-day Europe. Nenderthals lived from 200,000 to 30,000 years ago.BS-W59307...$270

C..Australopithecus afarensis.SkullAfarensis lived between 3.6 and 2.9 million years ago. The australopithecines are only known from Africa and are believed to be the earliest known true hominids. None have ever been found in Europe or Asia. They had ape-sized brains; their average cranial capacity ranged from 413 to 530 cc. They had strong jaws with large teeth. Like modern gorillas, the adult males were much larger than the females. BS-W59305...$225

D..Kenyanthropus platyops.SkullDiscovered by Meave Leakey and her team in 1998 west of Lake Turkana, Kenya. K. platyops was described in the March 2001 issue of Nature as a new genus dating back to the middle Pliocene, 3.5 MYA., challenging A. afarensis "Lucy" as the direct ancestor of modern human.BS-W59308...$270

La.Chapelle-aux-Saints-.Homo (sapiens) neanderthalensisDiscovered in France in 1908 this is one of the most controversial skulls to be excavated. Described as dull-witted, brutish and ape-like at the time; he was at least 40 years old, suffered from severe arthritis and had a mis-shapen face due to missing part of his jaw and many teeth. Despite these deforming conditions, it is now clear that the La Chapelle-aux-Saints man was much more like us in appearance than had been believed.22 x 16 x 22½ cm; 0.9 kg.BS-VP751/1

The partial mandible comes from a different dig but is clearly from the same species. Discussions continue as to whether the specimen is an Australopithecus boisei or a Paranthropus boisei.

& www.

Steinheim-.Homo (sapiens) steinheimensisFound in 1933 in the area of Steinheim, Germany the skull was crushed on the right side, but once pieced together revealed some interesting characteristics. The most obvious aspect being the face does not protrude as much as most Neanderthals. The brow ridges, however, are somewhat thick. This mix of traits obviously shows a transition from a primitive to a modern form. The original was between about 25 to 35 years old and possibly female.19 x 12½ x 21½ cm; 0.7 kg.BS-VP753/1

Sit and Reach TestThe Sit and Reach Test is the most common measurement of the flexibility of the lower back and hamstring muscles. Standard sit and reach tests use a reference point and test procedure which does not allow for variations in the length of arms and legs of the person being tested.

With the Acuflex I, the variables are limited and one can truly test trunk and hamstring flexibility.

Features of this unit include:• Maximum reach indicator• Foot plate for greater accuracy• All-steel construction• Adjustable tension on reach indicator• Scales that read in inches and centimeters• Designed to do both the modified sit and reach test and the traditional sit and reach testBS-W46010A $250

Apple Blossom (Malus pumila)Enlarged 5x life-sizeFamily: Rosaceae

Species of woody plants and rose plants include trees, bushes, and hardy perennials. Rosaceae species are subdivided into 4 subfamilies: Spiraeoideae, Rosoideae, Maloideae (pomaceous fruit, e.g. apple) and Prunoideae (stone fruits, e.g. cherry). The flowers mostly feature a pentameric perianth and numerous stamen.

An apple flower is the perfect model of 5’s in Fibonacci’s sequence. The flower is radial, five-whorle and five-part. Five sepals form the inner whorle, next to them are 5 petals. There are typically 5 inflorescence on a branch. The stamina are bunched in five’s, this model has 4 sets of stamen. While individual flowers vary in numbers of sets they are always in multiples of five. Hawthorn (Crategus monogyna) and Cherry (Cerasus vulgaris) have similar flowers. A spectacularly beautiful model, the rounded white leaves are barely tinted with pink. The powder-coat paint on the stem and anthers give this model a realistic look & feel. 10 x 9 x 16½”, .91kg,BS-T21016 $175

Cherry Blossom with Fruit (Prunus Avium)Enlarged 7x life-size, 3-partFamily: Rosaceae

This model shows the blossom of the sweet cherry (3-parts) enlarged 7 times as well as a cherry fruit enlarged 3 times. The cherry blossom can be split into two halves to reveal the removable ovary with style and stigma. 32.5 cm; 0.6 kgBS-T21019 $262

Potato Flower (Solanum tuberosum)Enlarged 8x life-size, 2-partFamily: Solanaceae

In nature, the Potato flower branches usually divide into two stalks, each with multiple flowers. The gramopetalous corolla’s 5 points are radially symmetrical, marked by yellow lines that equally transverse & divide. The 5 stamen sets are fused to form a conical stamina. The corolla and stamina detach to reveal the superior pistil. The powder coated paint on the stamina and stem give life-like texture that provides realism to the model. 5 petals, 5 sepals, 5 sets of stamen all fall into Fibonacci’s sequence. Similar flower structures to the Potato flower are Peppers (Capsicum annuum) and Tomatoes (Lycopersicum esculentum).7 x 7 x 15”, ½kg, BS-T21014 $103

Rapaseed or Canola Seed (Brassica napus ssp. Oleifera)Enlarged 12x life-size, 3-partFamily: Brassicaceae

Brassicaceae, formerly known as Crucifereae, is named for its Cross-like (Cruciferous) flower. Unique in the plant world for having 4 petals, Rapaseed does not follow Fibonacci’s sequence.

The fruit of Rapaseed is refined to make Canola oil. With 30-40% high sugar content it makes an excellent source of food for pollinators. Rapaseed is self-fertile, and has shown in testing that pollination with its own pollen results in seeds 19% heavier than pollination from another Rapaseed. Brassicas are unique for containing more agricultural crops than any other family, consisting of Cabbage, Radish, Mustard, Horseradish, Turnips, Kohlrabi, Brussel Sprouts, Broccoli, & Cauliflower. Rapaseed lends itself to teaching the formidable “Triangle of U” concept. One petal is removable for detailed study of the stepal and stamen. A ripe pod, magified 3x life-size is depicted in cross section, removable from base.11 x 9½ x 14”,BS-T21020 $255

& www.

Wild Rapa (Sinapis arvensis)Enlarged 12x life-size, 3-partFamily: Brassicaceae

The sepals and petals standing in two whorled circles form a cross-shape, leading to the former Cruciferous family name. The stamina are in two whorles. The two stamina in the outer circle are shorter than the four stamina in the inner circle. The ovary is divided by a wall and the ovules are linked to the edge of this wall.

Brassicas are unique for containing more agricultural crops than any other family, consisting of Cabbage, Radish, Mustard, Horseradish, Turnips, Kohlrabi, Brussel Sprouts, Broccoli, & Cauliflower. Cabbage (Brassica oleracea) and Mustard (Brassica nigra) have similar flowers. The carpel can be removed from the silique and disassembled into two pieces.13 x 13 x 14”, .75 kg, BS-T21012 $170

Sweet Pea (Pisum Sativum), Enlarged 7x life-size, 12-partFamily: Papilionaceae/Leguminoseae

The pea is one of the earliest cultivated crops, first harvested in the early Stone Age. There are over 17,000 members of the Papilionaceae family, named for its butterfly-like zygomorphic symmetry of the corolla. The corolla consists of petals, 2 wings, and the keel that comes from two petals which have grown together. Peas are also Legumes, meaning they form a symbiotic relationship with a rhizobium bacteria to fix nitrogen from the air into a form used in the soil. They thrive in low nitrogen, high pH environments in which other plants can’t survive.

This model has 11 parts and is mounted on a base. Use this model to teach the principals of genetics that Gregor Mendel discovered using Sweet Peas. Easily examine the Parent and F1 generations and discuss sexual and asexual reproduction.10 x 7 x 10½”, .3kg BS-T21026 $295

Celandine or Pilewort (Ficaria vema)Enlarged 10x life-size, 1-partFamily: Ranunculaceae

The family of Ranunculaceae depicts an ancient flower structure. Also known as both the buttercup or crowfoot family the number of the flower parts are indefinite, especially the male and female parts. In this case, the flower has 8 petals encased in 3 slim stepals. There are a number of stamina and pistils and the carpels are unfused. Looking down into the model, you can see the pattern of Fibonacci’s sequence in the spiraling pistils. Pilewort/Celandine due to its high Vitamin C content was originally thought to ward off scurvy.39 cm; 0.4 kgBS-T21017 $199

Dandelion (Taraxacum officinale)Enlarged 10 - 20x life-size, 3 individual modelsFamily: Asteraceae

Dandelion belongs to the Asteraceae family of composite flowers. Characterized by numerous florets arranged in a dense inflorescence that is contained by overlapping green bracts that open and close to protect the flower. The word dandelion refers to the large tooth-like indentations on the plant’s leaves and the bright yellow color of its flower head. The taproot, which can extend as much as 2 meters in depth, can be roasted in the fall and used as a substitute for coffee. Historically it was a precursor to hops used as a bittering agent in beer. The leaves are edible, though especially tasty in the spring. The milky sap of dandelions was used to purify the blood, cure stomach ailments, treat gall bladder and liver disorders.

The Dandelion model contains three separate models, each on their own base. The inflorescence is enlarged 10 times life-size. It contains up to 200 florets in its tight bracts. The florets has five lobes and are magnified to 20 times life-size. Through an intricate process of fertilization, the seed begins to mature. Shown at 20 times life-size the seed ripens and the beak grows to three or four times its length. When it opens, the Dandelion’s characteristic puff ball allows dissemination of its seeds by wind. Flower: 8 x 10 x 13.5” enlarged 10x, Floret: 5 x 5 x 13” enlarged 20x, Seed: 5 x 5 x 13” enlarged 20xBS-T21022 $427

Genuine Camomile (Matricaria chamomilla)Enlarged 10x life-size, 2-partFamily: Asteraceae

Asteraceae or composite flowers are characterized by the torus, a series of florets arranged in dense heads, that resemble a single flower. A very old plant, Chamomile has existed since prehistoric times. It has been used medicinally to reduce inflammation, eliminate cramping, promote digestion & acts as a sedative. The flower is constructed by a single row of lingulate florets, on the outer edge, female petals that attract the pollinators to the center hermaphroditic fertile flowers.

The white ray florets are furnished with a ligule, while the disc florets are yellow. The composite flower head is shown enlarged 10x and halved to allow outer and inner views. A single tubular fertile flower is shown enlarged 70x for detailed examination of its inner structures. Chamomile is the perfect flower to teach the natural application of the Fibonacci sequence. The tubular florets mature in sequence from the outside in a spiral configuration to the center. The model shows the maturation process from immature inner flower out to mature stamen.12 x 9 x 11½”BS-T21023 $305

Oak (Quercus robur)Enlarged 25x life-size, 1-partFamily: Fagaceae

Oak trees have both male and female flowers on the same tree. The male flowers hang down while the females protrude up. Its flowers are adapted to wind-pollination, so they are not bright and flashy to attract insects. The female flowers form no inflorescence, they remain green and do not produce nectar. Female flowers, once fertilized, go on to become acorns. The cupule, the cuplike structure holding an acorn is a modified, woody involucre. Beech (fagus silvatica) and Hazel (Corylus avellana) have similar flowers.6.5 x 13 x 11”, 1.3 kg, BS-T21011 $190



Wheat (Triticum aestivum)Enlarged 15x life-size, 5-partsFamily: Gamineae

The narrow, sharp and parallel-running leaves are typical of monocotyledonous grasses. Flowers of most grasses are adapted for wind pollination. The spike is made of 2 or 3 flowered ears. The ears are covered by two glumellata, while the flowers are covered by stiff protective hairs called awnes. In some species like barley, the awns can contribute significantly to photosynthesis. There are three stamina and a pistil with a large surface area. As the flower matures the stamina protrude from the center glumella and prostrate. The individual ears can be separated for a detailed view of the immature stamen and pistil.

Global wheat production for 2008-09 is projected at a record 656 million tons, up 8 percent from 2007-08, making it a very important plant to study for global food consumption. Rye (Secale cereale) and Barley (Hordeum vulgare) both have similar flowers.6 x 8 x 21”, 1kg.BS-T21009 $349

B. Center of Gravity PlateFor introducing the concept of center of gravity and determining centroids. The plastic plate has six boreholes and washable labeling.BS-U15032 $16

Torsion ApparatusFor studying static and dynamic torsion as well as the limit of elasticity of wires. The apparatus consists of a fixed clamping device for test wires and a rotatable protractor disc with a clamp. The horizontal assembly is used for static measurements and for determining the limit of elasticity, the vertical assembly for dynamic torsion measurements. A preset torsion is compensated for by a counter-torque during static measurements. When the limit of elasticity has been exceeded, permanent deformation of the wire is the outcome. The apparatus is used as a rotating pendulum during dynamic torsion measurements (vertical assembly). In order to vary the moment of inertia, the protractor disc can be loaded with additional weights. By determining the oscillation period, the dynamic torsion properties of the tested material can be ascertained.

Projectile LauncherExperimental equipment for the quantitative investigation of projectile laws: vertical, horizontal and angled launch, recording of flight trajectories depending on launch angle and projectile range.

Three different reproducible launch speeds, continuously adjustable launch angles, constant height of trajectory at various angles since the launch point is coincident with pivot point of the cannon. Projectile is launched with almost no spin. With threaded holes on the bottom for attaching a photocell light barrier. The encapsulated design and the use of spherical plastic projectiles ensure that experiments are safe.

Horizontal launch: projectile height as a function of the projectile distance

Oblique launch: projectile height as a function of the projectile distance (launch angle: 45°)

Ballistic PendulumFor experiments on elastic and inelastic collisions and for performing projectile experiments using the projectile launcher. The lightweight anodized aluminum construction of the pendulum eliminates the need to use steel balls as projectiles. The plastic projectiles can be propelled from the launcher at three different speeds. The projectile speeds calculated from the launch speed and from the trajectory agree to within about ±3%. Additional weights can be used to change the length of the pendulum swing while the projectile speed remains constant. While conducting projectile experiments the launcher is attached to the rear of the ballistic pendulum. 5 preset launch heights of 5, 10, 15, 20 and 30 cm allow trajectories to be investigated quickly and easily. The equipment is attached to a bench via a clamp.

Projectile Motion | Mechanics


Deluxe Vertical and Horizontal Projectile MotionFor demonstrating superposition of motions. A launching spring rail is mounted on a wooden base and two steel balls are used as test bodies. Upon triggering the spring rail one ball starts to fall downwards and the other is simultaneously launched horizontally. Both balls hit the ground at the same time. Two holes in the base plate are provided for storing the balls.

Launcher SExperimental apparatus for studying vertical and horizontal trajectories as well as trajectories starting at intermediate angles. Also demonstrates the independence of the horizontal and vertical components of motion (for projectiles). Including stand rod and bench clamp. Provides for three different launch velocities. Angle of launch can be adjusted to any arbitrary angle and read off from a protractor scale with a plumb line. The projectile ball is held in place by a magnet until the moment of launch so that the height of the trajectory is independent of the launch angle. When a projectile is launched, a second ball can be re-leased simultaneously from the other side of the launcher that then descends in free fall. The latter should strike the floor at the same time as the projectile if the launch angle is horizontal.

Free-Fall ApparatusApparatus for measuring the time it takes for a ball to fall a certain distance using a digital timer. Very easy to set up and use but nevertheless highly accurate. Includes 3 steel balls. A micro-magnet holds the ball in its start position. Three contact pins under the release mechanism ensure that the start position of the ball can be reproduced and act as the contacts of a switch that opens when the ball is released, thus triggering the beginning of the timing measurement. When the ball strikes the contact plate at the bottom, the timer is stopped. The ball is also held firmly on the plate so that it does not bounce. The height through which the ball drops can be adjusted to a fraction of a millimetre and read off a scale on the column.Height scale 20 – 960 mmScale divisions: 10 mmScale precision: 0.2 mmBalls: Steel, 16 mm dia.Dimensions: 200 x 130 x 1000 mm approx.Weight: 1.6 kg approx.BS-U8400830 $399

Kepler’s Second Law ExperimentAs an example of motion under the influence of a central force, the elliptical motion of a pendulum bob is recorded by the dust-marking method. This produces a trace with time-interval marks, and from the distances between these one can directly measure the velocity of the pendulum bob. Furthermore, it can be shown by a simple graphical analysis that the area swept by the radius vector of the pendulum in each time interval is constant, and is thus independent of the length of the radius vector.

Jet Nozzle (Flow Laminator)For generating an almost homogenous air flow for flow experiments in connection with an air flow generator (e.g. fan BS-U15425-115). The jet nozzle spreads the air blowing from the fan. The air thereby escapes from the tubular nozzles in the area of the plastic ring and mixes with the secondary air to form a total air current of a large diameter. The jet nozzle has no moving components, it does not produce any eddies and is very light (necessary for experiments on jet propulsion). The jet nozzle is suited for conducting almost all experiments connected with air currents, e.g. studying convection in bodies (in connection with the law of resistance and buoyancy of bodies BS-U8404260), flow resistance, aerodynamic paradox, and jet propulsion.

Laminar Flow ApparatusFor demonstrating and investigating the laminar flow properties of water. The emergence of currents in water, the flow of current in the case of straight

laminar flow and the overflow of differently shaped bodies can be studied. A constricted flow of current can also be demonstrated clearly.A rectangular piece of velour paper is placed in the apparatus consisting of an upper and lower trough. Owing to capillary forces, water from the upper trough is drawn in by the paper. The water flows down into the velour paper. The flow

of water in the upper level is marked with a dye at constant intervals. Owing to the low speed of flow (approx. 2 mm/s), the development of currents can be

observed with the help of the dye. After the velour paper has been dried, a lasting current pattern remains, which can be copied and evaluated.

BESTSELLERPythagorean CupPythagoras is known to most students today as the author of the Pythagorean Theorem (a2 + b2 = c2). There was far more to Pythagoras’ philosophy than this: he was a deep thinker on religion, the nature of the soul, and the harmony of the cosmos. With the “Pythagorean Cup” he illustrated to his students the virtues of moderation: when filled halfway, it retains its contents, but if it's too full, all of the liquid drains out through a hole in the bottom.

Our Pythagorean cup is made of hand-blown clear glass. The secret of the construction is a siphon, which is built in the center of the cup. Ideal for explaining to your students the principle of a siphon with an historical background.

“This pair of removable tuning forks with their matched resonators are well-made and can be used for many of the resonance demonstrations. The fork can be used alone or inserted in its resonator-- the quality of the resonance is superb! Excitation of the paired resonator is easily achieved by placing the open ends nearby. The movable mass can be used to produce beat frequencies over a wide range. This economical set is the one I’d hoped to find for my set of demonstrations.”

Includes measurement and evaluation software for Windows operating system. If the radiated waves are reflected or scattered from moving particles or bubbles in fluid flow, the Doppler shift in frequency can be detected. The equipment detects the scattered waves and generates an audio signal at a volume that reflects the amplitude of the reflected signal and a frequency that reflects the speed of the scattering. At the same time, the amplitude is also displayed on an LED bar display. Sensitivity and volume can be adjusted by means of appropriate controls. The controller can also pass on data to a PC for detailed recording and evaluation. During measurement the current LF Doppler signal is displayed. Evaluation is by means of a Fourier transformation in the frequency domain and the result can be interpreted as the distribution of velocity within the flow.Frequency: 2 MHzGain: 10 – 40 dBDisplay: LED bar display and acoustic signal with volume controlPC connector: Parallel, LPT, Sub D 25Mains voltage: 90 – 230 V, 50/60 HzDimensions: approx. 256x185x160 mm³BS-U10001 $6,900

Ultrasound | Acoustic & Wave Theory


Demonstrating the Concepts:Initially, the test object is subjected to vertical sound waves inside the water-filled sound trough. Only longitudinal sound waves are broadcast through the object and the transmitted amplitude of these waves is registered. If the test object is rotated, an increase in the angle of rotation leads to a decrease in the amplitude of the longitudinal sound waves and an increase in the propagation of transverse waves through the object. These waves appear on the amplitude display in the form of a second peak. The angle of total reflection of the longitudinal sound wave determines the speed of longitudinally transmitted sound. The angle corresponding to maximum transmission amplitude of the transverse sound wave will establish the speed of transversely transmitted sound. If rotation is continued, the transverse sound component may also undergo total reflection. These two speeds of sound can be used to determine the test object's shear modulus, modulus of elasticity and Poisson ratio. Compared with the speed of sound in water, the speed of the transversely propagated sound is almost the same in polyacrylate, higher in aluminum and lower in polyoxymethylene.

Available test blocks include polyacrylate (included), aluminum (BS-U10022) and polyoxymethylene (POM) (BS-U10023).

Ultrasonic EchoscopeThis device is used to conduct ultrasound experiments with the 1 MHz (BS-U10015) and 4 MHz (BS-U10017) transducers. It is equipped with a built-in transmitter and receiver, time-dependent amplification (time-gain-control or TGC) as well as an integrated analog-to-digital converter and microprocessor for connection to a measurement and evaluation computer via its parallel port.

The ultrasonic transducers are connected via robust snap-in jacks, their frequencies are identified automatically by the ultrasound scanner. Ultrasound tests can be conducted in reflection mode (pulse-echo principle) or through-transmission mode. The transmitting power and amplification can be adjusted over a wide range. Losses in the intensity of the irradiated ultrasonic pulses can be compensated by means of time-dependent amplification (time-gain-control or TGC). The threshold value, starting value, rise time and gain time are adjustable.

The most important function signals (trigger, TGC, low-frequency (amplitude) signal, high-frequency signal) are output to BNC sockets and can be displayed on an oscilloscope.

Specifications:The ultrasonic echoscope includes a software program supported by the following operating systems: 95/98/ME, Windows NT/2000 and Windows XP. The equipment can be connected to a computer's parallel port (LPT). Received signals (sonogram) and simultaneous TGC signals are displayed on the screen. The sonogram can show the low-frequency (amplitude) signal, high-frequency signal or both simultaneously as functions of time or penetration depth. All currently set device parameters are displayed on the screen. Additional program functions allow a display of 2-dimensional ultrasonic cross-sections (B-images) and the time curves of moving reflection layers (time-motion technique). Ultrasonic transducers and the laptop are not included. Available with USB or Serial port.

An RS232c male to female cable (not supplied) is needed for connecting the teslameter to the RS232 connector on the computer.

TeslaMeter Software – The teslameter software automatically collects data from the teslameter. The software automatically recognizes the range selected. An autoscaling feature on both axes means you don’t have to worry about which range to select. Data is taken at a constant rate of 1 Hz for up to 2 hours. A manual mode is also provided. This allows you to plot magnetic field vs. position. Data is taken each time a key is pressed. You can then move the probe, press the key and get a reading at that position. Autoscaling of both axes is also provided in this mode. The software is extremely easy to use. The TeslaMeter 2000 comes with complete operating instructions, a transverse probe, and an external power supply. The Zero Gauss Chamber and software are also included.

High Strength MagnetizerDesigned to remagnetize horseshoe magnets and bar magnets which have become demagnetized during use. It produces a very strong magnetic field to magnetize cobalt alloy (for example, AlNiCo), and other similar metals. It can also be used to magnetize other ferromagnetic materials such as iron, and alloys of iron containing nickel and cobalt. It uses a silicon-controlled-rectifier circuit to provide a minimum of 100 A of current during each half cycle of the power line frequency. Because of the large field generated, only a short period of time is required to magnetize the magnets. It has an On/Off Switch, momentary Switch and Pilot Light. Instructions are printed on the rear of the chassis, and the magnetic polarity for each well, N for north, and S for south, are indicated on the front panel. The Magnetizer operates from 115V, 50/60 Hz, and has a 6 ft. (1.8m) line cord.

Using the renewable energy produced from the solar panels, an electrolyzer disassociates deionized water into its constituent components of hydrogen and oxygen. Energy is stored in the form of hydrogen which is then utilized by the fuel cell. The hydrogen and oxygen are recombined into water by the fuel cell and release heat and energy in the process. The electrical energy released is then demonstrated by the fan on the end of the kit. The Fuel Cell Demonstration System uses PEM membrane technology and does not require caustic KOH (Potassium Hydroxide) as an electrolyte, only distilled water. The Fuel Cell Demonstration System comes fully assembled with solar module, PEM electrolyzer, H2 and O2 storage tanks, PEM fuel cell, and a fan all mounted on a convenient base.BS-U109501 $385

Heat & Thermodynamics | Thermal Expansion & Radiation

Giant Sized Crookes RadiometerOur radiometer is twice as tall as the competitor‘s, allowing for more visible and exciting demonstrations. This classical piece of equipment vividly shows the differential absorption of radiation and expansion of residual gas. The glass globe is 99% evacuated and houses a balanced set of four vanes. Each vane has one black and one white face. When illuminated with an ordinary incandescent bulb, the vanes transform the radiant energy into kinetic energy, as the black sides absorb more heat and thus expand the neighboring gas at a greater rate than the white sides.Height: 21 cmFlask diameter: 8 cmBS-U14300 $39

Apparatus for Demonstrating the Greenhouse EffectFor demonstrating the effect of greenhouse gases on the absorp-tion of infrared radiation. The experiments are very simple, lucid and can be conducted very quickly. The radiation emitted (short-wave infrared and visible light from an incandescent reflector lamp [part 1] or long-wave infrared from a black metal disc [part 2]) passes through either air or greenhouse active butane gas in a metal tube. The radiation is partly ab-sorbed and can be registered by the thermopile. Significant differences in the absorption of radiation in part 1 (corresponding to the incident solar radiation on Earth) and part 2 (corresponding to the infrared radia-tion emitted from Earth) can be demonstrated. The heavy absorption of long-wave infrared radiation by greenhouse-active butane gas impres-sively demonstrates the mounting rise in temperature of the Earth‘s atmosphere (greenhouse effect).

BESTSELLERCritical Point ApparatusPrecision equipment for investigating compressibility and liquefaction of a gas. Measurements allow the critical point for the gas to be determined as well as the recording of isotherms for an adiabatic p-V diagram (Clapeyron diagram).The gas used for testing is SF6 – sulphur hexafluoride. This has a critical temperature of 319 K (46° C) and a critical pressure of 3.76 MPa (37.6 bar). It allows the experiment set-up to be simple, robust and understandable so that both qualitative investigations and precise measurements can be made. SF6 is completely non-hazardous and can be used without reservation in lessons and labs. The pressure is applied by a hydraulic system using castor oil of medicinally authorized quality.BS-U104001 $5,962

• No mercury needed! Traditional equipment used to examine the critical point are filled with mercury which is harmful both to nerves and kidneys.• Using two scales (one stationary and one co-rotational) any change in volume can be read off with an accuracy of 1/1000 of the maximum volume (15.7 ml).• Class 1.0 manometer (max. 1% deviation from the end value of the scale) with 160 mm diameter and a display gauge up to 60 bar.• Drill hole with 6 mm diameter for commercially available thermometer or temperature sensor.• The theoretically long-life of the measuring cell amounts to 70 bar; while the theoretical bursting pressure point is above 200 bar.• Dimensions: Base plate 37 x 20 cm, height 39 cm. Weight: approx. 6.9 kg.

System Details:The equipment for studying the critical point consists of a transparent measuring cell of a highly sealed, pressure-resistant design. The volume of the measuring cell can be modified by turning a fine-adjustment wheel and can be read from one fixed and one rotating scale to an accuracy of one thousandth of the maximum volume. The measuring cell and hydraulic system are isolated from one another by a conical rubber seal which curls when there is a change in pressure. This design means that any pressure difference between the measuring cell and the oil reservoir is negligible in practical terms. A manometer thus measures, not the pressure of the actual gas but that of the oil, thus eliminating any need for a dead space within the gas reservoir. The manometer scale is large enough for it to be read in a lecture hall setting. The measuring cell is surrounded by a transparent chamber of water which can be controlled by a water bath to maintain temperatures during the experiment with a high degree of accuracy. The temperature can be read using a digital thermometer in the case of demonstration experiments, and also checked for consistency.

The fact that volume , pressure and temperature can all be read with a high degree of accuracy means that accurate p-V diagrams or pV-p diagrams can be recorded. When observing transitions from gas-to-liquid or vice versa, the lack of dead space means that the very first drop of liquid or the last bubble of gas can be observed. A cold light is supplied to illuminate the cell. The flush valve is separate from the inlet which means the test gas can be introduced to the chamber without picking up any other gas impurities.

Heat PumpDemonstration model for showing how refrigerators and heat pumps work. Electri-cal compression heat pump consisting of compressor with drive motor, vaporizer, condenser and expansion valve. These components are connected in a closed system by pipes and mounted on a base board. Evaporator and condenser are constructed as copper tubing spirals and each of them is submerged in water filled buckets serving as heat reservoirs for determining the energy absorbed or emitted. Two large manom-eters display the pressure ratios of the coolant in both heat exchangers. A protective overpressure switch disconnects the heat pump from the circuit when overpressure reaches 15 bars. In order to observe also the properties of liquids and gases (refriger-ants) and the processes by which they are converted from one to another the heat pump is equipped with viewing ports. These allow you to see inside the pump and observe the state of the refrigerant immediately after the evaporator or condenser. May be used as an air-water or water-water heat pump.

Magic MirrorThe Western Han “Light-Transmitting” mirror known as the Magic Mirror has a history of more than two thousand years. It is a miracle created by the ingenious Chinese craftsman in Western Han Dynasty (206 B.C-24.A.D.) through combining the optical and mechanical principles with superb metallurgical technology. These wonderful mirrors are able to reflect the decorative pattern cast on their backs onto a white screen when sunlight is shining on their polished fronts. The fabrication technology of this magic mirror was lost in Song Dynasty (960-1127 A.D.) and had remained a mystery until 1975.

Speed of Light | Optics

Light Speed MeterUsing electronic time-delay measurement. The oscillator for the LED light pulse, the photoreceptor

and the calibrated quartz crystal oscillator generator accurately timed square-wave pulses are integrated into one compact

housing. The transmitted signal is reflected via an internal and external reflector and superimposed onto the original signal. Due to this, the external main reflector, thanks to its numerous, small triple-prism reflectors, can be set up without difficulty simply judging by eye. The evaluation is carried out with a dual-channel oscilloscope capable of recording at least 70 MHz (e.g. BS-U43569). On the basis of the determined differential delay, the speed of light can thus be calculated.

Deflection of electron of velocity v in a magnetic field B by a Lorentz-force F into a closed circular path of radius r.

Basic PrinciplesDetermine the specific charge of the electron! In the Fine Beam Tube, the electrons move along a circular path in a uniform magnetic field. The tube contains neon gas and the neon atoms are ionized along the path of the beam as they collide with the electrons. This collision excites the atoms which emit light and allow the electron path to been seen. The radius of the path can then be measured directly with a ruler. Since the accelerating voltage U of the electron gun and the magnetic field B are known, it is possible to calculate the specific charge of an electron e/m from the radius of the circular path.

Experiment topicsDetermine the specific charge of an electron• Demonstrate the deflection of electrons in a uniform magnetic field along a closed circular path• Determine the Helmholtz coil current IH in relation to the accelerating voltage U of an electron gun where the electrons are moving in a circular path of constant radius r• Determine the specific charge of an electron e/m from the measurements

Franck-Hertz Tube with Neon Filling Mounted on BaseFor demonstrating that free electrons colliding with neon atoms emit energy in quantized packets and for determining the excitation energy of the 3p0 or 3s1 states at about 19 eV. When excited, these states emit visible light due to the energy drop from intermediate levels to a ground state at an excitation energy of about 16.7 eV. The light so emitted is in the red-yellow region of the spectrum. Bands of light develop between the control grid and the accelerating grid. The plane-parallel geometry of the grids means that these bands can be viewed through a window.

Isotope GeneratorThis Cs-137/Ba-137 m Isotope Generator is used to demonstrate the properties of radioactive decay. Based on the original Union Carbide patented design, it offers exceptional performance, ease-of-use and safe operation.

Each generator contains 10 µCi of Cs-137, which represents one Exempt Quantity, making it free from specific State and Federal licensing. The generator can produce up to 1000 small aliquotes of the short lived Ba-137m isotope with a half-life of 2.6 minutes.

Each generator is supplied with 250 mL of eluting solution (0.9% NaCl). The parent isotope Cs-137 with a half-life of 30.1 years beta decays (94.6%) to the metastable state of Ba-137m. This further decays by gamma emission (662 keV) with a half-life of 2.6 min. to the stable Ba-137 element. During elution, the Ba-137m is selectively “milked” from the generator, leaving behind the Cs-137 parent. Regeneration of the Ba-137m occurs as the Cs-137 continues to decay, re-establishing equilibrium in less than 1 hour.

Approximately 30 minutes after elution, the residual activity of the Ba-137m sample has decayed to less than one thousandth of its initial activity, making it safe for disposal. When used with the eluting solution supplied, bleed through of the parent Cs-137 is less than 50 Bq/mL, affording a long working life. Each kit is supplied with the generator, syringe, tube, 250 mL of solution and a storage case.BS-U41500 $328

Instrumentation | Function Generators

Function Generator/Digital CounterThe microprocessor controlled generator can be used alone or together with the PC. This new generator does not have a frequency range switch. With just one knob, or by means of the PC interface, the frequency can be adjusted continuously within the whole range. The frequency range 0 to 130 kHz can be adjusted with a resolution of 1 or 2 Hz. In the special frequency function from 0.10 to 20 Hz, the frequency can be adjusted with 0.01 Hz. The user has the possibility to select sine, rectangle, triangle or positive square as waveform. The output impedance can be adjusted either to 50 ohms or 600 ohms. Additionally the generator gives a separate TTL signal output.

• The amplitude can be digitally adjusted alternatively in Vrms -, Vp - or Vpp voltage. • The frequency range from 1 to 130 kHz has a programmable sweep function that

sweeps in steps of 1 to 10 kHz with step rate of 0.05 to 5 seconds.• The sweep function can be used e.g. with the microphone input for investigation

of the amplitude characteristic as well as resonance phenomenon (data are analysed after the experiment by means of the PC). The generator is provided with BNC sockets in inputs and outputs.

The output amplifier is protected from overload, short-circuit, induction voltages from coils as well as spark discharges. The amplifier is provided with BNC sockets in the input as well as safety sockets in the output when switched off.

The Perfect Balance of Science and ArtEcoSphere is the world's first totally enclosed ecosystem - a complete, self-contained and self-sustaining miniature world encased in glass. Easy to care for, an EcoSphere is an incredible learning tool that can provide powerful insights about life on our own planet... and provide a glimpse of technology that's shaping the future of space exploration. EcoSpheres are works of art, living treasures to own or give to someone special. Each one is carefully crafted to achieve an aesthetic, meditative beauty that can soothe any environment, including home, classroom or office.

The Inside StoryInside each EcoSphere are active micro-organisms, marine shrimp, and algae each existing in a clear "soup" of filtered sea water. Because the EcoSphere is a self-sustaining ecosystem, you never have to feed the life within. Simply provide your EcoSphere with a source of light and enjoy this aesthetic blend of art and science, beauty and balance.

The Ideal Environment for LifeAn EcoSphere is easy to care for making it an ideal gift. All that is required to keep your world in perfect balance is light - indirect light or artificial light will do. Because the living organisms within the EcoSphere utilize their resources without overpopulating or contaminating their environment, the EcoSphere requires only minimal care.

A Powerful Education ToolBy observing and understanding the delicate balance that occurs within their EcoSphere, we can better appreciate the complex relationships that occur in our larger world. How diverse elements of the biological community work together to sustain themselves, how all things necessary for life can be produced within a sealed system, and how waste products are broken down and recycled.

Small spheres have a six month replacement policy while all others have a one year replacement policy. Please contact Customer Service for details on shipping and replacement.
