Advantages of Porex Virtek® PTFE Membranes. Robust and durable sintered PTFE due to 3D matrix construction. Naturally hydrophobic for waterproof venting. Self-supporting membrane that is easy to handle and omni-directional. UL-94 flammability and UL-746C weatherability listings. Reflecting property to diffuse light or radiation.
What membrane filter pore size should I use for sterilization? Regardless of the membrane filter material, always use a 0.2 µm pore size membrane filter as the final filter for any sterilizing filtration. The 0.2 µm membranes used in Thermo Scientific™ Nalgene™ filters have been tested and shown to retain 100% of a challenge of 1 X 107
Filson 0.2 micron PTFE filter has absolute micron rating of 0.2, therefore most particles larger than 0.2 micron will be removed. In addition, our 0.2 micron PTFE filter has a high filtration efficiency up to 99.99%, and you can get a overall lower cost than conventional filters. Material: Polytetrafluoroethylene ( PTFE) Micron Rating: 0.2 micron.
Due to its strength and broad chemical compatibility, PTFE is commonly used in membrane filters. While PTFE is known for its high strength, the addition of a high-density polyethylene (HDPE) backing offers improved filter handling characteristics. Hydrophilic LCR and Omnipore™ PTFE membranes are typically used for filtering aqueous solutions.
The usage of POREX materials maximizes the performance for many sensor applications, including gas absorption, effective venting, precise diffusion, electrolyte holding and wicking, catalyst support, and reflective media. Our customizable solutions for sensor manufacturers can be tailored to specific applications or devices – and seamlessly integrated with many manufacturing processes.
Superior Performance. Supor EKV filters feature 0.2-micron-rated validated sterilizing-grade membranes. With standard 5- and 10-inch format filters utilizing a laid-over-pleat membrane geometry in capsules and cartridges for high flow rates and throughput performance, their PES membrane ensures very high compatibility over the whole pH range

Dissolution Filters. POREX ® Dissolution filters are used in conjunction with pharmaceutical tablet and capsule products to help filter contaminates during the dissolution testing process. Heavy metal free POREX Dissolution Filters are available in cannula, circular/disk and filter frit designs in a wide variety of porosities.
POREX porous plastic sheets are commonly used for filtering, diffusing, venting, wicking, or as membrane supports. The filtration varies depending on the micron size material selected. These sheets are chemically resistant to most acids, alkalis, solvents and hydrocarbon based fuels. They can be die cut into any 2D geometric shape.
verify chemical compatibility with a specific filter under actual use conditions. Because chemical compatibility is affected by many variables (including temperature, pressure, concentration, and purity), various chemical combinations prevent complete accuracy. Caution Alcohol residues that are allowed to dry on a filter may cause stress cracks.
