PES Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk
GVS SKU: FJ25BNPPS002AD01

GVS ABLUO Polyethersulfone (PES) Syringe Filters, 0.22 µm, 25 mm, 500/Pk - FJ25BNPPS002AD01

GVS casts its own microporous membranes and assembles them into finished syringe filters under one roof, rather than sourcing either component externally. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. PES's open pore layout leaves proteins less surface to contact while blocking bacterial passage at its finest micron ratings and loads aqueous buffers with zero pre-wetting delay. The PP housing sustains efficient flow on viscous samples while leaving no seam for sample to bypass the membrane and stands firm against aqueous acids, bases, and alcohols during regular handling. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Aromatic sulfone backbone underlies stability across the full pH range
• Inherent hydrophilicity allows instant aqueous wetting with no pre-wetting step
• DNA and RNA pass through with negligible adsorptive loss
• Chemical breadth spans alcohols, glycols, and aqueous buffers
• Sterilizing-grade PES membrane lots are challenge-tested against Brevundimonas diminuta to qualify 0.2 micron retention

Housing Characteristics

• Maintains dimensional form and seal integrity through elevated-temperature sample preparation at its rated limit
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation

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.

• PFAS Water Testing - PES filters process aqueous samples for EPA Method 1633A PFAS testing without added fluorinated background.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Cell Culture - Reduces the risk of mycoplasma contamination in growth media, supporting healthier cell lines and more reliable experimental outcomes.
• Media Preparation - Facilitates rapid sterilization of tissue culture additives, lowering contamination risk during sensitive laboratory work.
