Introduction
The microporous membrane filter is mainly used for the filtration of mobile phase and samples during the chromatographic analysis, especially for preventing chromatographic column and infusion pump line system and sample valve from pollution. They are widely used for gravimetric analysis, microanalysis, colloid separation and sterility test. The filer membrane made of different materials, such as polyetherdsulfone (PES), nylon6, Nylon66 MCE and polytetrafluoroethylene (PTFE), PVDF etc. can be provided.
PES

Polyethersulfone (PES) membranes are hydrophilic, low protein binding and stable in alkaline pH. Available in a 0.8µm pore size, the PES membrane is recommended for aqueous applications and for biological samples. They are also an alternative choice for users requiring a filter that exhibits extremely low protein binding characteristics. This kind of membrane is imported from MEMBRANA company in Germany.
