GD/X 13mm Syringe Filter, Cellulose Acetate Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6880-1302

Whatman GD/X Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 13 mm, 150/Pk - 6880-1302

Whatman fits more prefiltration capacity into the GD/X housing without enlarging it, a space-efficient answer for samples too demanding for one filtration pass. A sterilizing-grade syringe filter delivers point-of-use sterile filtration in a single-use format, without the housing and gasket maintenance a reusable stainless steel filter holder requires. Cellulose acetate delivers sterile-grade retention at the rated sub-micron pore size while binding less protein than mixed cellulose ester of similar size and stays smooth with low extractable background. The polypropylene housing routes flow to minimize backpressure in service and presses snugly against the membrane during the pass. When sterile or particle-free preparation matters at the bench, sterilizing-grade retention delivers it in a single pass.

Technical Specifications

• Dilute samples reach the analyzer at their true, unadsorbed concentration
• Tolerates methanol and ethanol at typical laboratory working concentrations
• Withstands autoclave sterilization at operating temperatures up to 135°C
• Accepts gamma irradiation or ethylene oxide exposure as alternative sterilization methods to autoclaving
• Clarifies aqueous HPLC mobile phases and injection samples ahead of column exposure.

Housing Specifications

• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Stable across the full aqueous pH range in routine sample work
• Gamma-stabilized polypropylene formulations tolerate terminal irradiation sterilization without embrittlement or discoloration
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
