PTFE 0.22 Syringe Filter Supplier
PTFE is hydrophobic and needs to be pre-wetted before being used with aqueous solvents. Used for: corrosive solvents, strong acids, alcohols, alkalis, aromatic hydrocarbons. Not suitable for: water-based samples.
The filter in the picture is a 13mm 0.22 PTFE Syringe Filter. This type of syringe filter is often used for filtration before analysis of chromatographic consumables, and the PTFE membrane is chemically resistant to almost all solvents, acids and alkalis. The membrane has low extractability and good thermal stability.
