0.2 μm Sterilizing-Grade PTFE Gas Disc Filters
The Alioth Alipore® TAHF Series features a hydrophobic and chemically inert PTFE (polytetrafluoroethylene) filter membrane. Through rigorous liquid bacteria retention validation, the product effectively retains microorganisms and particles even in wet or humid gas streams. Engineered for high mechanical strength, it withstands repeated steam-in-place (SIP) sterilization cycles.
The TAHF 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
Typical Applications
Sterile gas filtration
Sterile filtration of organic solvents vent
