GD/X 25mm Syringe Filter, Cellulose Acetate Filteration Medium, 0.45um (1500 pcs)
Whatman SKU: 6881-2504

Whatman GD/X Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6881-2504

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Cellulose acetate holds a uniform pore structure for consistent results while clarifying particulates at the rated pore size and keeps protein adsorption very low across the run. The PP housing prevents sample bypass under rated operating pressure while maintaining a low-dead-volume internal flow path and holds extractables low for sensitive analyses. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Smooth surface with low extractables and a uniform pore structure
• Very low protein binding supports high recovery of dilute samples
• Naturally hydrophilic surface wets readily with aqueous samples
• Absolute pore-size rating gives consistent retention across protocols
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Tough polypropylene body tolerates repeated handling at the bench

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.
