LabExact Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10072

Many syringe filters ship with lot-specific quality documentation, giving analysts documented traceability beyond what an ad hoc bulk filtration setup typically provides. The PES membrane loads aqueous buffers with zero pre-wetting delay while tolerating aliphatic alcohols, glycols, and aqueous buffers and clears particulate matter above its coarse cutoff threshold. Polypropylene construction resists chemical degradation from routine sample matrices and leaves no seam for sample to bypass the membrane. 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

• DNA and RNA pass through with negligible adsorptive loss
• Absolute pore size rating holds consistent across every lot
• PFAS extractables test non-detectable under EPA Method 537.1
• Ionic extractables from the membrane stay very low
• Non-ionic surface avoids charge-driven protein binding of positively and negatively charged membrane types

Housing Characteristics

• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion
• Resists stress cracking from aqueous salt and buffer solutions
• Withstands ethylene oxide gas sterilization without embrittlement or structural damage
• Impact-tolerant polypropylene body withstands routine bench handling without damage

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.

• Serum Filtration - Clarifies serum and plasma samples quickly while retaining critical proteins needed for accurate downstream analytical testing.
• 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.
• 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.
• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
