Polytetrafluorethylene (PTFE), Sterile, Hydrophilic
Polytetrafluoroethylene (PTFE) syringe filters are inherently hydrophobic but are also available in hydrophilic options. PTFE membranes are very resistant to solvents, acids, and bases and are ideal for filtering non-polar liquids and gases, including filtering and de-gassing chromatography solvents.
