Pura Disc 13mm PVDF Syringe Filters, 0.2um, 500 Pk SKU: 6792-1302

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.2µm, 13mm - 6792-1302

Eliminate the risk of microbial contamination in your upstream workflows with the Polyvinylidene Difluoride (PVDF) Whatman Puradisc, 13mm, Polyvinylidene Difluoride Syringe Filter, 0.2µm 500/pk, optimized for sterile filtration protocols. 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. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.
