PALL AP-4302 Acrodisc Syringe Filters with PTFE Membrane - GxF/0.45 µm, 25mm (1000/pkg)

Syringe filters with 0.45 μm or 0.2 μm membranes are used in analytical chemistry to filter samples before analysis, protecting instruments and extending chromatography column life.

• The description claims that filtering a sample prior to injection into analytical instrumentation helps protect sensitive parts of the instrument and reduces system downtime.
• The description claims that PTFE membrane is highly chemically compatible for the filtration of harsh solvents and repels water, making it unsuitable for aqueous solutions.
• The description claims that the hydrophobic nature of PTFE membrane makes these syringe filters suitable for gas filtration and as a moisture barrier in venting applications.
