PES Syringe Filter w/ Glass Fiber Prefilter, Sterile, 0.45µm, 13mm, Luer-Lok, 100/Pk
LabExact SKU: LE-IWT-ES10212

LabExact Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10212

Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. PES delivers sharp cutoff at rated pore size while staying stable across the pH 1 to 14 range and pairs fast flow with reduced protein adsorption. The PP housing sustains efficient flow on viscous samples while preserving sample chemistry across the flow path and stays inert across common laboratory solvents. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Membrane Characteristics

• Non-ionic surface avoids charge-driven protein binding of positively and negatively charged membrane types
• Ionic extractables from the membrane stay very low
• Absolute pore size rating holds consistent across every lot
• Chemical breadth spans alcohols, glycols, and aqueous buffers
• PFAS extractables test non-detectable under EPA Method 537.1

Housing Characteristics

• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• Rigid polypropylene body maintains its geometry through routine filtration pressure

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on.

• 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.
• 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.
• Life Science Prep - Speeds processing of viscous biological solutions, improving laboratory workflow efficiency during busy sample prep days.
• Serum Filtration - Clarifies serum and plasma samples quickly while retaining critical proteins needed for accurate downstream analytical testing.
