GD/X 25mm Syringe Filter, Nylon Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6870-2504

Whatman GD/X Nylon Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6870-2504

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Nylon arrives in economical bulk packaging for high-volume routine filtration while drawing aqueous samples through without a pre-wetting step and holds dimensional stability under rated backpressure. The polypropylene housing contributes minimal extractables to the filtrate while resisting aqueous acids, bases, and alcohols and sustains efficient flow on viscous samples. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Stable across the pH 3 to 12 operating range
• Low extractable contribution to sensitive analytical preparations
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• High tensile strength for stability under elevated differential pressures
• Alkaline-resistant across a broad range of aqueous buffers

Housing Specifications

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

Filtering particulates upstream protects the column investment your methods depend on. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.
