GD/X 25mm Syringe Filter, PVDF Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6873-2504

Whatman GD/X PVDF Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6873-2504

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. PVDF holds up to alcohols and mild hydrocarbon solvents while keeping analyte adsorption low for clean recovery and draws aqueous mobile phases through without pre-wetting. Polypropylene construction resists chemical degradation from routine sample matrices and maintains housing integrity through the filtration run. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Ultra-low protein binding preserves dilute analytes for maximum recovery
