Pura Disc 13mm PVDF Syringe Filters, 0.45um, 100/Pk SKU: 6779-1304

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 13mm - 6779-1304

Streamline your sample preparation workflows with the Polyvinylidene Difluoride (PVDF) Whatman Puradisc, 13mm, Polyvinylidene Difluoride Syringe Filter, 0.45µm 100/pk, constructed to handle high particulate loads while maintaining rapid throughput. Driving this clarification performance is a hydrophobic Polyvinylidene Difluoride (PVDF) membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
