LabExact Polyethersulfone (PES) Syringe Filters, 0.45 µm, 30 mm, 100/Pk - LE-IWT-ES10313

Many syringe filters ship with lot-specific quality documentation, giving analysts documented traceability beyond what an ad hoc bulk filtration setup typically provides. PES's low binding comes from surface chemistry, not the base polymer and handles strong bases across a broad aqueous range. The PP housing sustains efficient flow on viscous samples while leaving no seam for sample to bypass the membrane and stays inert across common laboratory solvents. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Membrane Characteristics

• High flow rate pairs with a low extractable background
• Inherent hydrophilicity allows instant aqueous wetting with no pre-wetting step
• DNA and RNA pass through with negligible adsorptive loss
• PFAS extractables test non-detectable under EPA Method 537.1
• Absolute pore size rating holds consistent across every lot

Housing Characteristics

• Housing rated for reliable filtration under syringe-applied backpressure at its maximum operating pressure
• Translucent housing wall allows visual confirmation of sample flow during filtration
• Medical-grade polypropylene with broad chemical compatibility
• Rigid polypropylene body maintains its geometry through routine filtration pressure

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last.

• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• 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.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Serum Filtration - Clarifies serum and plasma samples quickly while retaining critical proteins needed for accurate downstream analytical testing.
• Life Science Prep - Speeds processing of viscous biological solutions, improving laboratory workflow efficiency during busy sample prep days.
