Pura Disc 13mm PVDF Syringe Filters, 0.45um, 2000 Pk
Whatman SKU: 6765-1304

Whatman Puradisc PVDF Syringe Filters, 0.45 µm, 13 mm, 2000/Pk - 6765-1304

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The PVDF membrane tolerates common chromatography solvents without degradation and minimizes protein binding for high analyte recovery. The PP housing keeps the fluid path low in extractable contamination while preventing sample bypass under rated operating pressure and routes flow to minimize backpressure in service. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Mechanically durable membrane holds integrity under filtration pressure
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Low extractables preserve a clean chromatographic baseline
• Thin membrane structure sustains high flow for fast sample throughput

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Low extractable contribution protects sensitive downstream analyses
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service
