GD/X 25mm Sterile Syringe Filter, PES, 0.2um (50 pcs)
Whatman SKU: 6896-2502

Whatman GD/X Polyethersulfone (PES) Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 6896-2502

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. PES accepts water-based reagents without surfactant preconditioning while providing sterile-grade retention at sub-micron pore sizes and minimizes protein binding for high analyte recovery. The polypropylene housing contributes minimal extractables to the filtrate while staying inert across common laboratory solvents 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

• Sterile-grade retention at sub-micron pore sizes
• Stable across the full pH 1 to 14 operating range
• High flow rate with low extractable background for clean preparations
• Absolute pore size rating gives consistent results across protocols
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run.
