Pura Disc 13mm H-PTFE Syringe Filters 0.2um, Hydrophilic, 2000 Pk SKU: 6774-1302

Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 13mm - 6774-1302

Ensuring the biological integrity of sensitive media begins with reliable filtration, and the Hydrophilic Polytetrafluoroethylene (PTFE) Whatman Puradisc™ Syringe Filter, 13mm, 0.2µm, 2000/pk is engineered to deliver sterile effluents with every use. To achieve this medical-grade standard, the filter utilizes a Hydrophilic Polytetrafluoroethylene (PTFE) 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. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
