Whatman SKU: 6871-2504

Whatman GD/X Nylon Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6871-2504

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Nylon wets on contact with aqueous samples through its hydrophilic surface while supporting high-volume routine filtration and clarifies particulates at the rated pore size. The polypropylene housing holds a reliable seal against the membrane edge and keeps the fluid path low in extractable contamination. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Low extractable contribution to sensitive analytical preparations
• High tensile strength for stability under elevated differential pressures
• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Integrated glass-fiber prefilter increases dirt-holding capacity

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.
