Microporous membrane membrane operations include dead-end filtration (vertical flow filtration) and cross-flow filtration (tangential flow filtration).
Dead-end filtration is mainly used for fluids with small solid content and general processing scale. Most ptfe sterilizing filter membranes are made disposable.
The commonly used filtration mobile phase and disposable syringe filter membrane for analysis is dead-end filtration.
The polytetrafluoroethylene microporous membrane is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
