LabExact Polyethersulfone (PES) Syringe Filters, 0.22 µm, 17 mm, 100/Pk - LE-IWT-ES10310

A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. PES handles strong bases and oils across a broad aqueous range and safeguards sterility by retaining bacteria at fine pore ratings. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while holding its seal true run after run and routes flow to minimize backpressure in service. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.

Membrane Characteristics

• Chemical breadth spans alcohols, glycols, and aqueous buffers
• Finest available pore ratings achieve aseptic-grade filtration performance
• Ionic extractables from the membrane stay very low
• PFAS extractables test non-detectable under EPA Method 537.1
• Mechanical strength keeps the matrix intact under vacuum or pressure

Housing Characteristics

• Stable across the full aqueous pH range in routine sample work
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation
• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

Fine particulates that slip through raise your system backpressure and bring maintenance forward. Upstream buffer clarification keeps your run from stalling on particulates that slipped through across routine and validated analytical methods.

• 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.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
• Cell Culture - Reduces the risk of mycoplasma contamination in growth media, supporting healthier cell lines and more reliable experimental outcomes.
