Validated Autoclave Vent Filter for Critical Applications
Jul 17 2012
Porvair Filtration Group, leaders in the design and manufacture of filtration and separation materials and products, has announced the launch of VentafilTM, a hydrophobic ePTFE membrane filter specifically designed for sterile venting of autoclaves and storage tanks.
VentafilTM cartridges, designed with an easy to fit ∏" BSP male thread, act as a sterile vacuum break at the end of autoclave sterilisation cycles commonly used in Biopharmaceutical and healthcare applications.
Independently validated in accordance with PDA, HIMA and ASTM F838-05 guidelines, VentafilTM has proven to be 100% retentive during rigorous liquid bacterial challenge tests. To mimic conditions of use, VentafilTM cartridges have also been validated to retain air-borne bacterial spores and viruses.
The design of the VentafilTM cartridges provides exceptional mechanical strength as demonstrated through repeated steam sterilisation in-situ at temperatures of up to 135°C (275°F) for 100 cycles at 20 minutes per cycle.
Steam sterilisation in the reverse direction for in excess of 70 cycles in a venting application, without loss of integrity, has been independently validated by customers.
