PTFE 0.2μm Sterilizing-Grade Cartridge Filters

Data Download：

The Alioth Alipore® TAHF series features a hydrophobic and chemically inert PTFE (polytetrafluoroethylene) filter membrane. This product efficiently retains microorganisms and particles in wet or humid gas through stringent liquid bacteria retention verification. It offers high strength and resistance to multiple steam sterilizations in place. The TAHF series is suitable for sterile gas filtration and organic solvent filtration with strict quality requirements in pharmaceutical applications.
