GD/X 13mm Syringe Filter, Nylon Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6871-1304

Whatman GD/X Nylon Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6871-1304

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Nylon stays stable across the pH 3 to 12 buffer range while holding consistent retention across mixed-phase samples and resists particle shedding through extended cycles. The PP housing stays inert across common laboratory solvents and buffers and maintains housing integrity through the filtration run. 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
• Stable across the pH 3 to 12 operating range
• High tensile strength for stability under elevated differential pressures
• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Low extractable contribution to sensitive analytical preparations

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
