Vent Filters Protect Your Lab Environment
Use vent filters from Pall Life Sciences for venting receiving vessels, isolation or environmental chambers, bioreactors, fermentation tanks, carboys, and other small containers. Use in-line for low-pressure sterile air/gas delivery to instruments and culture vessels, bioisolation of a vacuum source, flushing instruments, and cleaning parts.
- Self-contained, compact filter devices provide high efficiency removal of airborne bacteria and particulate under dry or moist conditions.
- Hydrophobic membranes prevent passage of aerosols, protecting equipment and staff. Hydrophobic membrane choices include:
- PTFE – Offers a high level of hydrophobicity and assures the best system performance when used as a sterile barrier in venting or particulate control. PTFE will not absorb moisture that can cause premature reduction of air flow.
- PVDF – Can be gamma irradiated.
- Glass Laminate – The most economical choice also provides the highest air flow rates.
- Air flow is a critical performance parameter. Effective Filtration Areas (EFAs) range from 7.5 to
300 cm2, allowing users to select the appropriate vent size for their application.
- Rugged polypropylene housings have broad chemical compatibility.
- AcroPak™ 300 capsule is 100% integrity tested to provide the high level of confidence you require.
- Acro 50 vent devices with Emflon II membrane are stable up to 5 mRads gamma irradiation.
The most important considerations when selecting a gas or vent filter are air flow rate and particulate/microorganism retention.
Vent Filters Maintain Sterility
Vent filters provide a sterile barrier for air or gases entering or exiting vessels such as bioreactors, fermentation tanks, or carboys. These maintain the sterility of the interior environment and protect the atmosphere from contaminants within the vessel.
Considerations of Selecting Vent Filters
Pall offers self-contained, compact filter devices for high efficiency removal of airborne bacteria and particulate under dry or moist conditions. The most important considerations when selecting a gas or vent filter are air flow rate and particulate or microorganism retention. The membrane material in the filter must provide sufficient surface area or open space to accommodate the air flow required by the system. The filter should also efficiently retain particles and aerosol droplets, and, if sterile air or gas is required, retain bacteria.
Vent Filtration Air Flow Performance
In venting and air filtration applications, air flow is a criticial performance parameter. Pall's products offer Effective Filtration Areas (EFAs) ranging from 7.5 to 300 cm
