GD/X 13mm Syringe Filter, PES, 0.2um (150 pcs)
Whatman SKU: 6876-1302

Whatman GD/X Polyethersulfone (PES) Syringe Filters, 0.2 µm, 13 mm, 150/Pk - 6876-1302

Whatman ties GD/X prefiltration performance to one closely held fiber-grade standard applied at every production run, keeping results repeatable from one manufacturing lot to the next. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. PES's native polysulfone needs a surface treatment before it wets while leaving proteins less surface area to contact and stays stable across the pH 1 to 14 range. Polyolefin construction sheds virtually no extractable material into the sample while leaving no seam for sample to bypass the membrane and holds its geometry through sample filtration at temperatures up to 121°C. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Finest available pore ratings achieve aseptic-grade filtration performance
• Chemical breadth spans alcohols, glycols, and aqueous buffers
• Inherent hydrophilicity allows instant aqueous wetting with no pre-wetting step
• Absolute pore size rating holds consistent across every lot
• Ionic extractables from the membrane stay very low

Housing Characteristics

• PP housing rated to 121°C holds its geometry through high-temperature sample preparation and processing.
• Optimized internal geometry minimizes backpressure in service
• Stable across the full aqueous pH range in routine sample work
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

• PFAS Water Testing - PES filters process aqueous samples for EPA Method 1633A PFAS testing without added fluorinated background.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Tissue Processing - Prepares biological tissue homogenates smoothly, managing high protein and cellular debris for cleaner downstream analysis.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
