LabExact Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10065

A syringe filter's small hold-up volume limits sample loss, a meaningful difference when working with a limited or precious sample. PES's low binding comes from surface chemistry, not the base polymer while producing crisp cutoff at its micron rating and tolerates aliphatic alcohols, glycols, and aqueous buffers. The PP housing sustains efficient flow on viscous samples and preserves sample chemistry across the flow path. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.

Membrane Characteristics

• Sulfone backbone's hydrolytic stability tolerates repeated autoclave steam sterilization cycles
• Mechanical strength keeps the matrix intact under vacuum or pressure
• PFAS extractables test non-detectable under EPA Method 537.1
• DNA and RNA pass through with negligible adsorptive loss
• Non-hydrogen-bonding surface avoids the polar adsorption nylon's amide backbone causes

Housing Characteristics

• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Optimized internal geometry minimizes backpressure in service
• The seal formed against the membrane blocks bypass at rated operating pressure
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on.

• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• 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.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Serum Filtration - Clarifies serum and plasma samples quickly while retaining critical proteins needed for accurate downstream analytical testing.
