Nylon CA(Cellulose acetate)• Hydrophilic property• Ideal for aqueous(Non-acidic) or organic sample• High protein binding, Not used when protein recovery is

important, Commonly used to for general lab filtration of HPLC

• Naturally Hydrophilic• Low protein binding suitable for aqueous samples• Nitrate free suitable for ground water filtration• Excellent choice for maximum protein recovery, bind less

protein than PVDF• Ideal for tissue culture media and sensitive biological

sample

PTFE(Polytetrafluoroethylene) PES(Polyethersulfone)Hydrophobic PTFE• Strong hydrophobic• Strong chemical stability and inertia• Strong acid and alkali solvent filtration• Chemical resistance to all solvent, Ideal for filtering gas

Hydrophilic PTFE• Inorganic solvent with strong chemical causticity filtration• Mixed solvent filtration in HPLC(Acetonitrile/Water)• Alkali solvent filtration

• Lowest protein binding• Low binding of protein and nucleic acid, faster than

PVDF, excellent flow rates• Suitable filtration for tissue culture media• Broad chemical resistance , aggressive solvents

PVDF(Polyvinylidene difluoride) MCE(Mixed cellulose ester)• Good heat endurance and chemical stability• Strong hydrophobic, Non Aggressive aqueous, mild

organic solutions, Solvent mixture• Extremely low protein binding• HPLC sample, general biological filtration

• Filtration of aqueous sample, effectively bind trace protein

• Little resistance• Oil, Alcohol, and bacteria filtration and then inspect,

Particle Analysis Microbiology

PP(Polypropylene) GMF• Naturally hydrophilic membrane, Wide range of chemical

compatibility to organic solvents• Low no-specific absorbing membrane for maximum

protein recovery in critical analysis• Suited for biological sample filtration

Designed specially to filter high particulate solutions. With four layers, the first filter is a composite membrane of 10μm glass fiber and 1.0μm PP, the second prefilter is 0.7μm GF/F membrane media, the last one is filtration media as speci-fied.
