Pura Disc 25mm PVDF Syringe Filters, 0.2um, 200 Pk
Whatman SKU: 6747-2502

Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 25 mm, 200/Pk - 6747-2502

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. PVDF achieves sterile-grade retention at sub-micron pore sizes while minimizing protein binding for high analyte recovery and wets aqueous and HPLC samples on contact. The PP housing keeps the fluid path low in extractable contamination and maintains housing integrity through the filtration run. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Thin membrane structure sustains high flow for fast sample throughput
• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Sterilizing-grade retention at sub-micron pore sizes
• Mechanically durable membrane holds integrity under filtration pressure
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• 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 across routine and validated analytical methods.
