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.

The CPM venting filter, type BA, allows for 100 percent sterile venting of storage tanks and containers in many industries, typically the water and dairy industries. Equipped with the patented, flexible Ecofilter ® element, consisting of filter membranes in between segmented stainless steel disks, the BA offers the highest filtration efficiency and security.

Tetratex membrane microporous films are naturally hydrophobic and can be used as permeable water barriers for venting or breather filters for gas sensors, electronics and more. Donaldson's proprietary oleophobic treatment process also makes filter media repel oils.

PTFE Syringe and Vent Filters. The PTFE syringe filter is available with or without a glass fiber prefilter. PTFE membranes are hydrophobic and are designed to filter most aggressive solvents whether they are acid or base samples. Our 50 mm PTFE syringe is excellent for venting applications or protecting a vacuum pump from liquid contamination.

Carboy Vent Filter, 0.2 Micron. Compact filter for venting and solvent filtration applications Useful for maintaining purified water stored in carboys Features a Teflon PTFE membrane Hydrophobic membrane permits sterile venting on a slow exhaust/liquid autoclave cycle of carboys up to

Venting membranes made from porous PTFE can be excellently welded on plastic parts, thermally or using ultrasonic technology. Welding enables a highly durable connection between the membrane and the component, even under harshest conditions.

2020/10/13 · Our new hydrophobic and oleophobic polyethersulfone membranes are designed for fast air filtration or sterile venting while preventing any liquid passage or condensate blockage. Their high performance and superior gamma stability make them a very efficient and powerful alternative to PTFE and will help you to increase your process and product security.

50 mm Filters with Superior Performancefor Demanding Applications. Reusable and autoclavable. PTFE membrane and polypropylene housing have broad chemical resistance. Large surface area provides greater throughput and high air flow rate. Available with a variety of inlet and outlet connectors.

PTFE membrane is a thin, highly porous film that behaves as an absolute retentive membrane. Their inherently hydrophobic nature make PTFE membranes ideal for applications such as filtering gases, aqueous aerosols, protecting vacuum pumps, or sterile venting fermentation tanks. PTFE is inert.
