Whatman
Pura Disc 13mm PVDF Syringe Filters, 0.2um, 50 Pk SKU: 6791-1302

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.2µm, 13mm - 6791-1302

Designed for the stringent demands of cell culture and biological assays, the Polyvinylidene Difluoride (PVDF) Whatman Puradisc, 13mm, Polyvinylidene Difluoride Syringe Filter, sterile, 0.2µm 50/pk offers validated bacterial retention for confident sample preparation. Driving this efficiency is the integration of a hydrophobic Polyvinylidene Difluoride (PVDF) membrane, ensuring high recovery of sensitive samples while maintaining a sterile effluent. 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.
