0.2 μm Sterilizing-Grade PTFE Gas Filters

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.

Key Features and Benefits

Natural hydrophobic material
High gas flux and low-pressure drop
Reliable bacterial/particles removal efficiency
Excellent chemical compatibility
Resistance to multiple steam sterilization

Typical Applications

Bioreactors (inlet | outlet)
Storage tank venting
Filling equipment venting
Lyophilizer
Autoclave venting
Sterile filtration of organic solvents
