Whatman GD/X PVDF Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6872-2504

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Hydrophilic PVDF wets aqueous and HPLC samples on contact while delivering absolute particle cutoff at the rated pore size and holds up to alcohols and mild hydrocarbon solvents. The polypropylene housing routes flow to minimize backpressure in service while resisting aqueous acids, bases, and alcohols and contributes minimal extractables to the filtrate. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Low extractables preserve a clean chromatographic baseline
• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Absolute pore size rating gives consistent results across protocols
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Mechanically durable membrane holds integrity under filtration pressure

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification. Connect with our customer support technicians for chemical compatibility guidance and the right filtration product for your workflow.
