Description
PTFE (Polytetrafluoroethylene) is an inherently hydrophobic membrane excellent for the 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 it with deionized water.
