0.2 μm Radiation-Resistant PES Gas Filters
Alipore® TEHF Series filters consist of hydrophobic polyethersulfone (PES) membranes and have undergone rigorous liquid bacterial retention validation. They effectively retain microorganisms or particles in wet or humid gases, featuring high mechanical strength, radiation resistance, and tolerance to repeated autoclaving cycles. Ideal for sterile gas filtration in single-use systems for pharmaceutical applications, including sterilization of air, hydrogen, nitrogen, and other gases.
Key Features and Benefits
Hydrophobic material
Tolerance to 45 kGy gamma irradiation
Reliable bacterial retention and particle removal efficiency
High gas flux with low pressure differential
Excellent chemical compatibility
Typical Applications
Vent filter for single-use bags
Aeration of single-use reaction bags
Sterile filtration of gases (air/hydrogen/nitrogen, etc.)
