Acro Disc Syringe Filters w/ PVDF Membrane - 0.2um, 25mm, 200/Pk SKU: 4406

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.2µm, 25mm - 4406

When sample purity is non-negotiable, the Polyvinylidene Difluoride (PVDF) Syringe Filters serves as a reliable safeguard, effectively removing microorganisms from aqueous solutions. To achieve this medical-grade standard, the filter utilizes a Polyvinylidene Difluoride (PVDF) membrane that provides a sharp 0.2 cutoff necessary for sterilizing biological fluids. 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.
