Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 13 mm, 2000/Pk - 6765-1302

Whatman draws on Cytiva's broader manufacturing oversight while continuing a legacy of filtration work that touches laboratory research, environmental monitoring, and industrial processing alike. A sterilizing-grade syringe filter delivers point-of-use sterile filtration in a single-use format, without the housing and gasket maintenance a reusable stainless steel filter holder requires. PVDF holds up to alcohols and mild hydrocarbon solvents and loads aqueous mobile phases on first contact. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane while standing firm against aqueous acids, bases, and alcohols during regular handling and sheds virtually no extractable material into the sample. The bench setup stays free of autoclave cycles and housing-maintenance steps once a single-use sterilizing-grade filter handles the preparation.

Technical Specifications

• Cast membrane structure releases no fibers, unlike depth-media prefilters
• Low ionic extractables preserve baseline stability in conductivity-based ion chromatography detection
• Fluoropolymer chemistry resists microbial and fungal degradation
• Mechanically durable membrane holds integrity under filtration pressure
• Resistance to hydrolytic degradation exceeds that of nylon membranes

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Impact-tolerant polypropylene body withstands routine bench handling without damage
• The seal formed against the membrane blocks bypass at rated operating pressure

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last.
