Whatman SKU: 6875-2502

Whatman GD/X PTFE Syringe Filters, 0.2 µm, 25 mm, 150/Pk - 6875-2502

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Across analytical workflows, the syringe filter is where particulates leave the sample stream. The PTFE matrix handles concentrated acids and bases across demanding methods while providing bacterial retention in gas and vent streams and stays chemically inert against solvents, acids, and alkalis. The PP housing stays inert across common laboratory solvents and buffers and contributes minimal extractables to the filtrate. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Stable across a wide operating temperature range for demanding methods
• Filters aggressive organic solvents without swelling or breakdown
• Low extractables keep the chromatographic background clean
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Low extractable contribution protects sensitive downstream analyses

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.
