New Product Release

Recently, Alioth Alipore®TAHF polytetrafluoroethylene (PTFE) material sterilization grade cartridge filter elements (5 inches, 10 inches, 20 inches, 30 inches) are officially on the market to protect the safe production of drugs by pharmaceutical enterprises.

 

Alipore®TAHF sterilization grade cartridge filter element

 

gas, non-aqueous phase sterilization filtration

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
