GD/X 25mm Syringe Filter, PVDF Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6873-2502

Whatman GD/X PVDF Syringe Filters, 0.2 µm, 25 mm, 150/Pk - 6873-2502

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. The hydrophilic PVDF membrane draws aqueous mobile phases through without pre-wetting while minimizing protein binding for high analyte recovery and tolerates common chromatography solvents without degradation. The PP housing sustains efficient flow on viscous samples while contributing minimal extractables to the filtrate and stays inert across common laboratory solvents. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Thin membrane structure sustains high flow for fast sample throughput
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Absolute pore size rating gives consistent results across protocols
• Mechanically durable membrane holds integrity under filtration pressure

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.
