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 pairs a borosilicate fiber depth layer with the finishing membrane inside every GD/X unit, a construction meant to process loads heavy enough to clog a conventional one-stage filter. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. Cellulose acetate admits water-based reagents immediately, with no surfactant step and stays smooth with low extractable background. Low-extractable polypropylene keeps sample purity intact through the filtration pass while holding its seal true run after run and maintains a low-dead-volume internal flow path. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.

Membrane Characteristics

• Naturally hydrophilic surface wets readily with aqueous samples
• Biologically nontoxic cellulose ester provides a clean filtration surface
• Low extractable contribution keeps filtrate chemistry clean
• Cellulose ester backbone stable across aqueous pH range of 4 to 8
• Stable in aqueous saline, buffer, and protein solution matrices

Housing Characteristics

• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Thermal-bonded construction keeps adhesives out of the fluid path

Filtering particulates upstream keeps your column running longer between maintenance cycles. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation.
