Syringe Filters with Teflon (PTFE) Membrane

Syringe Filters are complete ready-to-use filter units with a polytetrafluoroethylene (PTFE) membrane.

The Teflon membrane is used for the filtration of harsh chemicals, including acids and non-aqueous solvents, as well as for the preparation of GC and HPLC samples.

Since it has low resistance to gaseous compounds, the membrane is also used for air and gas filtration (aeration and ventilation activity).

The PTFE membrane is inert and hydrophobic, but, by wetting it with ethanol, it can be used as a hydrophilic support.

Available in different diameters and porosities.

PP casing.

Available on request with hydrophilic PTFE membrane.
