Polyethersulfone (PES) Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Sterile, 50/Pk
GVS SKU: FJ25BSCPS002AL01

GVS ABLUO Polyethersulfone (PES) Syringe Filters, 0.22 µm, 25 mm, 50/Pk - FJ25BSCPS002AL01

Class 100,000 cleanroom conditions govern GVS's syringe filter and membrane production, held to the specifications its quality management system defines. A sterilizing-grade syringe filter delivers point-of-use sterile filtration in a single-use format, without the housing and gasket maintenance a reusable stainless steel filter holder requires. PES provides sterile-grade retention at the rated sub-micron pore size while leaving proteins less surface area to contact and handles strong bases across a broad aqueous range. A butadiene-toughened MBS body absorbs handling stress at the bench and forms a snug fit around the membrane to block bypass. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Ionic extractables from the membrane stay very low
• Aromatic sulfone backbone underlies stability across the full pH range
• Chemical breadth spans alcohols, glycols, and aqueous buffers
• Absolute pore size rating holds consistent across every lot
• Non-hydrogen-bonding surface avoids the polar adsorption nylon's amide backbone causes

Housing Characteristics

• Creep-resistant matrix holds seal geometry through the filtration run
• Transparent body lets the operator confirm full sample recovery
• Phthalate-free composition keeps a common LC-MS and GC-MS contaminant out of sample workflows
• Sub-wavelength core-shell rubber domains toughen the methacrylate matrix without introducing optical haze

A column clogging mid-run from unfiltered sample can cost you the rest of your analytical day. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.

Hydrophilic

• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• 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.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• PFAS Water Testing - PES filters process aqueous samples for EPA Method 1633A PFAS testing without added fluorinated background.
