PTFE is an inherently hydrophobic membrane excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples. Although this membrane is hydrophobic, it can be made hydrophilic by wetting the membrane with alcohol and then flushing with deionized water.
This 33 mm syringe filter with a Hydrophilic PTFE membrane, for non-sterile filtration on the Samplicity G2 system, has a 0.45 µm pore size used in preparation of aqueous & organic solutions prior to chromatography or other instrument analyses. Millipore

Solvent Filtration Membrane found in: Solvent Filtration Disposable Vacuum Bottle Top Filters, Semi-Prep Solvent Filtration Frits, Magna PTFE (Teflon).. Using 47mm membranes for filtering corrosive solutions, particulate removal from HPLC solvents, and filtration analysis with solid phase extraction disks.
Because of their low inherent levels of extractables, nylon membrane syringe filters are commonly used to filter samples that are intended for HPLC analysis. Nylon membrane syringe filters may not be suitable for all samples and are ideal for near neutral pH aqueous solutions and compatible nonaqueous solvents.
Hydrophobic PTFE Membrane Filter PTFE membrane media for filtration is made of PTFE (polytetrafluoroethylene), and were drawn 2-demension. It is micro-pore film. The PTFE membrane was laminated with great variety of fabric and paper. They are new filter
PTFE is a hydrophobic membrane that is chemically resistant to almost all solvents. It can be used with corrosive media, such as strong acids, alcohols, alkalis, and aromatics. The unit is readily available, allowing simple, fast and reliable HPLC or GC analysis of ultra-clean small-volume samples.
0.22 μm hydrophilic PTFE membrane filter bubble points are above or equal 0.1MPa and 0.06MPa respectively, diameters ranging from 13mm, 25mm, 47mm to 90mm, 142mm, 293mm. Hydrophilic PTFE membrane pore size is 0.22μm, 0.45μm and chemical compatibilities are superior to aqueous, organic solvents and mixed solvents.
