0.2 μm Sterilizing-Grade PTFE Gas Filters
The Alioth Alisafe® TCHF Series utilizes a hydrophobic and chemically inert PTFE (polytetrafluoroethylene) membrane. Through rigorous liquid bacteria retention validation, this product effectively retains microorganisms and particles in wet or humid gas streams. Engineered for high strength, it withstands multiple steam-in-place (SIP) sterilization cycles.
The TCHF Series is ideal for sterile gas filtration and the filtration of organic solvents with stringent quality requirements in pharmaceutical applications.
