Sterilizing-Grade Cartridge Filter(PTFE 0.2μm)
Sterilizing-Grade Cartridge Filter(PTFE 0.2μm)
Product Introduction
Alioth Alipore® TAHF series is composed of hydrophobic and chemically inert PTFE (polytetrafluoroethylene) filter membrane. This product can efficient retain microorganism or particles in wet or humid gas through stringent liquid bacteria retention verification. High-strength, resistant to multiple steam sterilization in place. It is suitable for gases sterile filtration and organic solvents filtration with strict quality requirements in pharmaceutical applications.
Product Properties
- Natural hydrophobic material
- High gas flux and low-pressure difference
- Reliable bacterial retention and particles removal ability
- Excellent chemical compatibility
Typical Applications
- Sterile filtration of N2、O2、CO2 and compressed air
- Breathing apparatus such as fermentor and liquid storage tanks
- Sterile filtration of freeze dryer and autoclaving equipment of exhaust gases
- Sterile filtration of most organic solvents
