GD/X 13mm Syringe Filter, Nylon Filteration Medium, 0.45um (150 pcs)
Whatman SKU: 6870-1304

Whatman GD/X Nylon Syringe Filters, 0.45 µm, 13 mm, 150/Pk - 6870-1304

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The nylon matrix holds consistent retention across mixed-phase samples while adding a layered prefilter for particulate-laden samples and ships in economical bulk non-sterile packaging. The polypropylene housing contributes minimal extractables to the filtrate while resisting degradation from routine sample matrices and prevents sample bypass under rated operating pressure. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Integrated glass-fiber prefilter increases dirt-holding capacity
• High tensile strength for stability under elevated differential pressures
• Stable across the pH 3 to 12 operating range
• Low extractable contribution to sensitive analytical preparations
• Alkaline-resistant across a broad range of aqueous buffers

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
