Membrane Type

Hydrophilicity

Features

Application Directions

Cautions

PES

Hydrophilic

Low protein adsorption, high flow rate, wide pH Range, high chemical compatibility, good heat resistance

For general culture media and aqueous solutions, polar or middle-polar solvents, neutral aqueous solutions

Should not be used for chloroform esters, amides and strong acids or strong bases.

PVDF

Hydrophilic

Wide practicability, good oxidation resistance and heat resistance

May be used for aqueous solutions and most solvents, including strong non-polar solvents. Ideal for preparations of HPLC and GC

Should not be used for strong acids and bases

MCE

Hydrophilic

Strong chemical compatibility and low protein adsorption, the optimum pH range is 3-6

Used for particle analysis of general culture media and aqueous solutions. HPLC sample preparation.

The set should not be used for filtrations of ethanol and alkaline solutions. The working temperature should not be over 40°C.

CA

Hydrophilic

High flow rate and heat stability as well as very low adsorption, stable within the range of pH 4-8

It may resist most alcohols and oils, and is suitable for sterling filtration of aqueous solutions, buffers, serum and culture media, as well as filtration of the moving phase of HPLCD.

The CA Membrane may accommodate a smaller volume of buffer since it has low hydrophilia.
