Whatman® membrane filters PTFE pore size 0.2 μm, diam. 47 mm
The 0.5 μm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes.

Only one extraction was sufficient. The suspension was vortexed for 30 s and centrifuged at 13,000 rpm for 10 min with a Hettich Mikro 120 centrifuge (Tuttlingen, Germany). After filtration on 0.22 μm polytetrafluoroethylene (PTFE) membrane filters (VWR International, Milan, Italy), the samples were analyzed by HPLC as reported above.

Available with either PP, PTFE or nylon membrane. Membranes are available in either 0,2 or 0,45 µm pore size, with the choice often made on analytical column packing size. If the column packing size is larger than 3 μm then use 0,45 μm, and if 3 μm or smaller then use 0,2 μm.
FAQs - FILTRATION
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
Acrodisc® Syringe Filters with PTFE Membrane - 0.2 µm, 13mm
The Acrodisc® syringe filter featuring a 0.2 µm PTFE membrane, prevents air bubble locks when filling sample vials. Purchase online - syringe filters with a filtration area of 1.0 cm², hold-up volume less than 14 µL and a 13 mm minispike outlet.
Corning Filtration Guide
biological fluids and gases is usually done with 0.2 or 0.22 µm pore filter membranes. Clarification and prefiltration of solutions and solvents is best accomplished with 0.45 µm or larger filter membranes. Prefiltration to improve filter performance can also be accomplished by the use of glass fiber prefilters that can be purchased separately.

Membrane Filters | VWR
Membrane filters serve as effective physical barriers that remove solids, viruses, bacteria, and other unwanted molecules. Specialized types are designed for softening, disinfecting, organic removal processing, and water desalination. The filters can be installed in compact, automated, or modular units. These strainers can be used as separators
