Specialized types are designed for softening, disinfecting, organic removal processing, and water desalination. The
Laboratory Filters : Waters
Membrane Type (PTFE, wwPTFE, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart). For aqueous samples, it is preferable to use a hydrophilic membrane (wwPTFE, PVDF, or Nylon) versus a hydrophobic membrane (PTFE).
The Lab Depot | Syringe Filters - Filtration
• PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases. • Very resistant to solvents as well as acids or bases. • Can be made more hydrophilic by flushing with alcohol, followed by water • Used for filtering and de-gassing chromatography solvents

Membrane Filtration: Choosing the Correct Type of Filter
Differences between Hydrophilic Membranes and Hydrophobic Membranes. A hydrophobic membrane, such as polytetrafluoroethylene (PTFE) will resist any aqueous sample, creating back pressure. Although it is sometimes possible to overcome this back pressure with additional force, there is a risk of membrane rupture and incomplete filtration.
