PTFE Syringe Filter 25mm × 0.22µm

The MSPT25-22 PTFE Syringe Filter is designed for high-performance filtration of aggressive chemical samples and organic solvents used in analytical laboratories. Equipped with a hydrophobic Polytetrafluoroethylene (PTFE) membrane and a 0.22µm pore size, it provides sterilizing-grade clarification while offering outstanding resistance to virtually all organic solvents, concentrated acids, and strong bases. The 25mm membrane diameter ensures efficient filtration of medium to large sample volumes with high flow rates and consistent performance. Its durable polypropylene housing provides secure, leak-free operation during routine laboratory workflows. The MSPT25-22 is particularly suitable for UHPLC sample preparation, environmental solvent extract filtration, and analytical applications requiring maximum chemical compatibility. For aqueous samples, the PTFE membrane should be pre-wetted with a water-miscible solvent such as methanol before filtration.
