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. | ||
