ValuPrep Syringe Filters 13mm, 0.45um, w/ wwPTFE Membrane, 1000/Pk SKU: 6614563

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 6614563

Simplify your laboratory inventory with the Polytetrafluoroethylene (PTFE) Syringe Filters, a truly universal filter capable of handling aggressive solvents and water-based samples alike. Central to this universality is the wwPTFE membrane, which remains chemically compatible with aggressive solvents while being fully water-wettable. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
