GD/X 13mm Syringe Filter, PES, 0.2um (150 pcs)
Whatman SKU: 6876-1302

Whatman GD/X Polyethersulfone (PES) Syringe Filters, 0.2 µm, 13 mm, 150/Pk - 6876-1302

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Low-binding PES preserves dilute proteins and analytes in the filtrate while handling strong bases across a broad aqueous range and achieves sterile-grade retention with high recovery. Polypropylene construction maintains a low-dead-volume internal flow path while preventing sample bypass under rated operating pressure and holds extractables low for sensitive analyses. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Sterile-grade retention at sub-micron pore sizes
• High flow rate with low extractable background for clean preparations
• Stable across the full pH 1 to 14 operating range

Housing Specifications

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

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
