Pura Disc 13mm PVDF Syringe Filters, 0.2um, 50 Pk
Whatman SKU: 6791-1302

Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 13 mm, 50/Pk - 6791-1302

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The PVDF membrane tolerates common chromatography solvents without degradation while drawing aqueous mobile phases through without pre-wetting and achieves sterile-grade retention at sub-micron pore sizes. The polypropylene housing holds a reliable seal against the membrane edge while keeping the fluid path low in extractable contamination and maintains a low-dead-volume internal flow path. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Thin membrane structure sustains high flow for fast sample throughput
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Low extractables preserve a clean chromatographic baseline

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses
• Thermal-bonded construction keeps adhesives out of the fluid path
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path before they reach the column inlet or detector.
