GD/XP Syringe Filter, Nylon Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6970-2504

Whatman GD/XP Nylon Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6970-2504

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. The nylon membrane clarifies particulates at the rated pore size while shipping in economical bulk non-sterile packaging and wets on contact with aqueous samples. The PP housing sustains efficient flow on viscous samples while resisting aqueous acids, bases, and alcohols and maintains housing integrity through the filtration run. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• High tensile strength for stability under elevated differential pressures
• Low extractable contribution to sensitive analytical preparations
• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Integrated glass-fiber prefilter increases dirt-holding capacity

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run.
