Features:

Membrane Material	Feature
PES	PES asymmetric filter membrane, hydrophilic filter membrane, high porosity, fast flow rate, low extractables, and low protein adsorption.
CA	CA limited chemical compatibility, low protein binding.
PVDF	PVDF has strong chemical compatibility, low protein adsorption, and high mechanical strength.
NYLON	Nylon is hydrophilic, has high mechanical strength, is resistant to alkali but not acid, and has strong protein binding.
PTFE	PTFE is extremely chemically compatible.

Membrane Material	Specific Usages
PES	Suitable for filtration of biological liquids such as serum and cell culture fluid; such as culture media, buffer salts, and protein solutions.
CA	Suitable for buffered salt solutions and protein recovery experiments.
PVDF	Suitable for filtration of some organic solvents and biological liquids.
NYLON	It is suitable for filtering buffer salt solutions and chemical reagents, but is not suitable for filtering key protein solutions.
PTFE	Suitable for filtration of strong acids and alkalis with low extractable content.
0.2um vacuum filter cup is used for liquid sterilization filtration.  0.45um vacuum filter cup is used for liquid clarification and filtration.
