GD/X 25mm Syringe Filter, PVDF Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6872-2502

Whatman GD/X PVDF Syringe Filters, 0.2 µm, 25 mm, 150/Pk - 6872-2502

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Across analytical workflows, the syringe filter is where particulates leave the sample stream. PVDF holds up to alcohols and mild hydrocarbon solvents while drawing aqueous mobile phases through without pre-wetting and preserves dilute proteins and analytes in the filtrate. The PP housing prevents sample bypass under rated operating pressure and routes flow to minimize backpressure in service. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• 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
• Absolute pore size rating gives consistent results across protocols
• Sterilizing-grade retention at sub-micron pore sizes

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
