Membrane Filtration: Choosing the Correct Type of Filter | Cytiva
PTFE, polyvinylidene difluoride (PVDF), and RC are compatible with a wide range of solvents commonly used in HPLC while remaining low in extractables. We have compiled compatibility tables listing material resistance to common solvents, making them useful for quick reference.
Performance and Protection - .NET Framework
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

Millex® hydrophilic PTFE syringe filters boast broad chemical compatibility and are HPLC-certified, guaranteeing low extractables. With their robust performance, these filters can be used for a variety of samples without the risk of membrane failure or sample contamination.
Phenomenex Filtration Part: Phenex™-PTFE 5mm Syringe Filters
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.
How to Select a Syringe Filter and How to Use it? (2020 Guide)
Feb 7, 2020 · PTFE Hydrophobic Filters Chemical Compatibility Chart >> PTFE Hydrophilic Syringe Filters 0.2 or 0.45um . Resisting nearly all corrosive chemicals makes PTFE syringe filters an ideal choice. However, natural hydrophobic PTFE has it’s disadvantages not letting aqueous solutions passing through while many of these chemicals are diluted with water.
