50mm PTFE Syringe Filter – Witec AG

Robust Filtration for Demanding Applications

These 50 mm syringe filters feature a durable polypropylene (PP) shell and a high-quality polytetrafluoroethylene (PTFE) filter membrane. They are surfactant-free and designed with bi-directional membrane support, combining a single or double-stepped barb inlet/outlet for secure syringe attachment.

These filters are ideal for filtering corrosive chemicals and solvents commonly used in GC and HPLC, as well as for sterile air or CO2 gas filtration. They also effectively protect instruments from aqueous solutions.
