GD/XP Syringe Filter, Nylon Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6971-2504

Whatman GD/XP Nylon Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6971-2504

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. Nylon wets on contact with aqueous samples through its hydrophilic surface while pairing with an integrated glass-fiber prefilter for turbid samples and tolerates alcohols and aliphatic and aromatic solvents. The polypropylene housing holds a reliable seal against the membrane edge while keeping the fluid path low in extractable contamination and maintains a low-dead-volume internal flow path. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Stable across the pH 3 to 12 operating range
• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Absolute pore size rating provides consistent results across filtration protocols
• Low extractable contribution to sensitive analytical preparations

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility
• Resists aqueous acids, bases, and alcohols in routine sample prep

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run.
