GD/X 25mm Syringe Filter, Cellulose Acetate Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6880-2502

Whatman GD/X Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 25 mm, 150/Pk - 6880-2502

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Cellulose acetate holds a uniform pore structure for consistent results and keeps protein adsorption very low across the run. The PP housing sustains efficient flow on viscous samples while contributing minimal extractables to the filtrate and stays inert across common laboratory solvents. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Sterile-grade retention at sub-micron pore sizes
• Naturally hydrophilic surface wets readily with aqueous samples
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Very low protein binding supports high recovery of dilute samples
• Smooth surface with low extractables and a uniform pore structure

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.
