Venting and Gas Filtration

Protecting Your Lab Environment

Vent filters can provide a sterile barrier for air or gases entering or exiting vessels such as bioreactors, fermentation tanks, or carboys. These filters maintain the sterility of the interior environment and protect the atmosphere from contaminants within the vessel.

Pall Life Sciences vent devices contain hydrophobic membranes that prevent the entry of water and aerosols into sensitive equipment; thereby reducing repairs and prolonging the life of the equipment. Vent devices also protect the lab environment; from aerosolized pathogens. For the protection of the laboratory environment and prevention of culture contamination, always use a Pall Life Sciences vent filter.

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.
