Filtres d'aération, PolyVENT™, Whatman™

Whatman PolyVENT disc filters 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
• 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.
