PolyVENT™ and SteriVENT™ are an integral filter product for sterile venting of vessels and tanks. These devices are constructed from a single, standardized set of materials – PTFE membranes and polypropylene housing – to simplify the approval process.
Features and benefits
- Pass the HIMA Challenge Test for Sterilizing Grade
- Retain > 107 CFU/cm2 Brevundimonas diminuta per ASTM F838-83 standards; this microbial retention is correlated to 100% integrity testing during manufacturing (rated in liquid). (100% integrity testing is carried out only on the capsules).
- Membrane made of hydrophobic 0.2 µm PTFE membrane
- Validated for 50 steam autoclave cycles; compatible with EtO
- Testable by Water Break Through (WBT) test or bubble point testing
- Pass USP Class VI biosafety tests for plastics
- Manufactured in clean room facilities
- Bidirectional and autoclavable
Applications
- Venting (filling)
- Isolation (incubators, autoclaves, lyophilizers, EtO sterilizers, fermenters)
- Electronics (gases)

Can be autoclaved at 121°C for 20 minutes (maximum 132°C). Multiple autoclave cycles are possible. However, the responsibility for reuse is with the operator. The device should be protected from cross contamination. An integrity test should be performed after autoclaving. Compatible with EtO sterilization. |
