GD/XP Syringe Filter, PVDF Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6972-2504

Whatman GD/XP PVDF Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6972-2504

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 delivers absolute particle cutoff at the rated pore size and tolerates common chromatography solvents without degradation. The polypropylene housing routes flow to minimize backpressure in service and keeps the fluid path low in extractable contamination. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Thin membrane structure sustains high flow for fast sample throughput
• Mechanically durable membrane holds integrity under filtration pressure
• Absolute pore size rating gives consistent results across protocols
• 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
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses
• Optimized internal geometry minimizes backpressure in service

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.
