PTFE membrane filters are naturally hydrophobic with excellent chemical resistance, making them the ideal choice for sterile venting of gases*, non-aqueous solvents, acids, and aggressive fluids.
- Thin, highly porous membrane filter
- Behaves as an absolute retentive membrane
- Inert to most agressive solvents, including strong acids and bases
- Operating temperature range: -120~260°C
- Use to sterilize gasses, vent gas from aqueous solutions, or sterilize or clarify aggressive chemicals
PTFE membranes are hydrophobic in nature and are effective barriers to microbes and particulate matter. The high titer reduction and water intrusion pressures allow the membrane to repel high surface tension liquids while venting gases. PTFE membranes are used in a variety of healthcare applications such as vents on IV filters and spike vents, protecting equipment and sensors from fluids and contamination. Material characteristics include broad chemical compatibility, excellent particle retention, easy handling and sealing, and compatibility with various sterilizing methods, making it a versatile material for applications which require a hydrophobic barrier. Whether you need to keep fluid confined while letting air or gas pass, or a sterile barrier, PTFE is the ideal membrane.
The laminated membranes are thicker for easy handling. These filters are chemically and biologically inert, stable up to 260°C (500°F) and naturally hydrophobic; they are very useful for aerosol sampling, air venting, and gas filtration, especially in environments also containing water vapor.
