GD/X 25mm Sterile Syringe Filter, PVDF Filteration Medium, 0.45um (50 pcs)
Whatman SKU: 6900-2504

Whatman GD/X PVDF Syringe Filters, 0.45 µm, 25 mm, 50/Pk - 6900-2504

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. PVDF holds consistent absolute retention at the rated pore size while holding up to alcohols and mild hydrocarbon solvents and preserves dilute proteins and analytes in the filtrate. The PP housing sustains efficient flow on viscous samples and resists degradation from routine sample matrices. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Low extractables preserve a clean chromatographic baseline
• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting

Housing Specifications

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

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.
