Quick selection guide for filter membrane

Filter membrane material

characteristic

Main purpose

Mixed cellulose membrane
（MCE/CN-CA0

The most commonly used water membrane. The pore size is uniform, the adsorption is very small, and it is not resistant to organic solvents and strong acid and alkali.

Purification, sterilization and filtration of aqueous solution, analysis and determination of particles in solution, and test of suspended solids.

Nylon membrane
(Nylon)

Uniform pore size, resistant to most organic solvents and acid. High strength (with supporting layer)

Filtration of aqueous or organic mobile phase, tissue culture medium, pharmaceutical industry, beverage and high-purity chemicals.

Polypropylene film
(PP)

Resistance to organic and strong acid and alkali, high membrane strength, fast flow rate, poor pore uniformity and low price.

General solid-liquid separation is suitable for working conditions with high impurity content. Activated carbon filtration.

Polyvinylidene fluoride membrane
(PVDF)

Good heat resistance and chemical stability, low protein adsorption rate, hydrophobic and hydrophilic.

Hydrophobic: gas and steam filtration.
Hydrophilicity: purification and sterilization of culture medium and reagent.

Polytetrafluoroethylene film
(PTFE)

The most extensive chemical tolerance, resistance to strong acid and alkali solutions.

Filtration of almost all organic solvents and water-soluble waves.

Polyethersulfone membrane
(PES)

High flow rate, low dissolution, no adsorption of protein and extract, no pollution to the sample.

Low protein adsorption filtration, high purity water terminal filtration, serum filtration, solution sterilization filtration.

Glass fiber membrane
(GF)

Large gas and liquid flux and high temperature resistance.

Atmospheric and smoke sampling.
