Whatman Puradisc PVDF Syringe Filters, 0.45 µm, 13 mm, 500/Pk - 6792-1304

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 syringe filter's small hold-up volume limits sample loss, a meaningful difference when working with a limited or precious sample. The PVDF membrane clarifies samples at the rated pore size while tolerating common chromatography solvents without degradation and suits HPLC sample preparation with immediate, reliable uptake. Polypropylene construction resists chemical degradation from routine sample matrices while maintaining dimensional stability through sample runs at temperatures up to 121°C and maintains a low-dead-volume internal flow path. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Technical Specifications

• Fluoropolymer chemistry resists microbial and fungal degradation
• Absolute pore rating ensures reproducible results between test runs
• Organic solvent resistance beats PES or nylon at comparable pore size
• Fluorinated polymer chemistry resists ozone, UV, and ionizing radiation
• Membrane structure maintains integrity from -35 to 160°C

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists stress cracking from aqueous salt and buffer solutions

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on. Ask about a quality certificate, lot documentation, or a blanket-order quote for your filtration order at any time.
