Acro Disc Syringe Filters w/ PVDF Membrane - 0.45um, 13mm, Minispike Outlet, 1000/Pk SKU: 4545

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 13mm - 4545

Streamline your sample preparation workflows with the Polyvinylidene Difluoride (PVDF) Syringe Filters, constructed to handle high particulate loads while maintaining rapid throughput. Facilitating rapid sample turnover, the hydrophilic Polyvinylidene Difluoride (PVDF) membrane structure ensures the 0.45 rating remains consistent even under pressure. 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.
