Overview
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.
ISCC+ certified Biobased polypropylene housing (25mm devices):
- 90% Biobased plastic resin.
- Biobased plastic resin is ISCC Plus certified using Mass Balance approach.
- The polypropylene accounts for 95% of the weight/composition of the syringe filters.
