The microporous membrane filter is mainly used for the filtration of mobile phase and samples during the chromatographic analysis, especially to avoid damaging the chromatographic column, infusion pumping system and sample valve. They are widely used for gravimetric analysis, microanalysis, colloid separation and sterility tests. The filter membrane of different materials, such as polyether sulfone (PES), nylon6, CELL,GF and polytetrafluoroethylene (PTFE), PVDF etc. can be delivered.
Material: borosilicate fiberglass
Thickness: 150--200 meters
Appearance: white
PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas sterilization. The membrane is laminated on a non-woven polypropylene backing fleece for improved strength and handling and can be used at temperatures up to 150ºC.
Features and advantages:
Lowest binding material available
Hydrophilic
High throughput
Strength and Dimension Stability
Uniform pore structure
