Whatman ™ PolyVENT disc filters from Cytiva are integral venting filters that work bidirectionally to prevent contamination from entering containers like fermentation vessels during incubation.
0.2 µm hydrophobic PTFE air filters are ideal industrial air filter media
Validated for 50 steam autoclave cycles; compatible with ethylene oxide (EtO)
Testable by water break through (WBT) test or bubble point testing
Passes USP Class VI biosafety tests for plastics
Manufactured in clean room facilities
Filtration area 500, 1000, and 2000 cm² to support a range of venting applications
Draining or filling of incubators, fermentation tanks, and other vessels requires a venting filter capable of preventing bacterial contamination. With an integral PTFE filter membrane, Whatman™ PolyVENT acts as an industrial air filter media for sterilization* of gases entering bioreactors such as fermentation tanks.
*Refers to sterilization by filtration for small sample use which is an industry term for filters of pore size 0.2 um or smaller as referenced in guidance such as EPA Guidance for Industry Sterile Drug Products Produced by Aseptic Processing — Current Good Manufacturing Practice Section IX, Part B (September 2004).
