Pura Disc 25mm PVDF Syringe Filters, 0.2um, 50 Pk SKU: 6746-2502

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.2µm, 25mm - 6746-2502

For critical applications requiring absolute sterility assurance, the Polyvinylidene Difluoride (PVDF) Whatman Puradisc, 25mm, Polyvinylidene Difluoride Syringe Filter, 0.2µm 50/pk series provides a verified barrier against bacterial contamination. Central to this performance is a hydrophobic Polyvinylidene Difluoride (PVDF) membrane with a precise 0.2 pore structure that ensures the complete removal of bacteria and fine particulates. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.
