GD/X 13mm Syringe Filter, PVDF Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6873-1304

Whatman GD/X PVDF Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6873-1304

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The hydrophilic PVDF membrane draws aqueous mobile phases through without pre-wetting while keeping analyte adsorption low for clean recovery and clarifies samples at the rated pore size. The polypropylene housing contributes minimal extractables to the filtrate while preventing sample bypass under rated operating pressure and sustains efficient flow on viscous samples. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• 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
• Thin membrane structure sustains high flow for fast sample throughput

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench.
