PTFE membranes are hydrophobic in nature and are effective barriers for microbes and particulate matter. Hydrophilic PTFE membranes are also available. The high titer reduction and water intrusion pressures allow the membrane to repel high surface tension liquids while venting gases.
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.
The Acrodisc ONE PSF syringe filter with wwPTFE membrane is automation-certified to ensure smooth operation and worry-free performance. Additionally, the wwPTFE membrane is also available in Nanosep ® spin devices for low volumes and AcroPrep™ Advance filter plates for
