Graduated Cylinder Used to measure exact volumes Measure the volume from the bottom of
the meniscus.
Meniscus
Watch Glass
used as a surface to evaporate a liquid, to hold solids while being weighed, or as a cover for a beaker
Test Tubes and Test Tube RackTest tubes are used to carry
out chemical reactions.When not in a test tube holder
or clamp, put test tubes in a test tube rack.
Burette
Dispense exact volumes of liquid.
They are used during a process called titration.
Volume measured from the bottom of meniscus
Ring Stand and Iron Ring
Provide structural support for various attachments that are usually used to hold glassware
The iron ring holds a wire gauze, triangle, or funnel on the ring stand.
Utility Clamp
Used to hold glassware in place on the ring stand.
Triangle
Rests on iron rings and are used to hold funnels during filtering or crucibles during heating.
Wire Gauze
Covers the iron ring to provide a flat surface for beakers when heating them.
Funnel
Can be used with filter paper to filter fluids. They can also be used for transferring fluids.
Crucible
Used to hold small amounts of a substance to be heated or dehydrated.
Striker
Produce sparks to light Bunsen burners
Bunsen Burner
Produce a flame used to heat, dehydrate, or sterilize substances in the lab
Hot Plate
Used to heat solutions.
Mortar and Pestle
Used to grind solids into powders
Thermometer
Used to measure temperature.
NOT FOR STIRRING!
Stirring Rod
Used for stirring chemicals
Scoopula
Used to transfer solids
Used to transfer small quantities of liquids
Disposable Pipette
The Test Tube Brush
FOR YOU to use to clean test tubes and graduated cylinders
Not for Mr. S or your parents
**A VERY IMPORTANT PIECE OF EQUIPMENT**
