GD/X 25mm Syringe Filter, Nylon Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6870-2502

Whatman GD/X Nylon Syringe Filters, 0.2 µm, 25 mm, 150/Pk - 6870-2502

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Nylon ships in bulk non-sterile packaging for routine clarification and sample prep while pairing with an integrated glass-fiber prefilter for turbid samples and stays stable across the pH 3 to 12 buffer range. Polypropylene construction maintains housing integrity through the filtration run and routes flow to minimize backpressure in service. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Non-sterile for routine clarification and sample prep
• Low extractable contribution to sensitive analytical preparations
• Integrated glass-fiber prefilter increases dirt-holding capacity
• Alkaline-resistant across a broad range of aqueous buffers
• Layered prefiltration sustains flow through turbid, particulate-laden samples

Housing Specifications

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

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 before they reach the column inlet or detector.
