GD/X 25mm Syringe Filter, Regenerated Cellulose Filteration Medium, 0.45um (1500
Whatman SKU: 6883-2504

Whatman GD/X Regenerated Cellulose (RC) Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6883-2504

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The RC membrane stays stable across the aqueous pH 3 to 12 range while keeping non-specific binding low for high analyte recovery and wets on contact with aqueous and solvent samples. Polypropylene construction resists chemical degradation from routine sample matrices while preventing sample bypass under rated operating pressure and keeps the fluid path low in extractable contamination. 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
• Naturally hydrophilic surface wets without pre-wetting in aqueous and solvent samples
• Stable across the aqueous pH 3 to 12 range
• Low extractables give a clean chromatographic background
• Low non-specific binding preserves dilute analytes for maximum recovery

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists stress cracking from aqueous salt and buffer solutions
• Medical-grade polypropylene with broad chemical compatibility
• Rigid polypropylene body holds its shape under manual filtration pressure

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep.
