Pura Disc 25mm Nylon Syringe Filters, 0.45um, 50 Pk
Whatman SKU: 6750-2504

Whatman Puradisc Nylon Syringe Filters, 0.45 µm, 25 mm, 50/Pk - 6750-2504

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. The nylon membrane clarifies particulates at the rated pore size and accepts water-based samples without surfactant conditioning. Polypropylene construction maintains a low-dead-volume internal flow path while resisting aqueous acids, bases, and alcohols and holds extractables low for sensitive analyses. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Non-sterile for routine clarification and sample prep
• Low extractable contribution to sensitive analytical preparations
• High tensile strength for stability under elevated differential pressures
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
