GD/X 25mm Syringe Filter, Cellulose Acetate Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6880-2504

Whatman GD/X Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 25 mm, 150/Pk - 6880-2504

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Across analytical workflows, the syringe filter is where particulates leave the sample stream. The cellulose acetate surface stays smooth with low extractable background while minimizing protein binding for high analyte recovery and stays stable across the pH 4 to 8 range. The PP housing sustains efficient flow on viscous samples and resists degradation from routine sample matrices. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

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

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on.
