LabExact Polyethersulfone (PES) Syringe Filters, 0.45 µm, 17 mm, 100/Pk - LE-IWT-ES10311

Because each syringe filter is dedicated to one sample, a failed or contaminated filtration stays isolated to its own analyst's run and leaves the next analyst's queue clear. The PES membrane loads aqueous buffers with zero pre-wetting delay while staying stable across the pH 1 to 14 range and maintains absolute retention accuracy at that pore rating. The PP housing stays inert across common laboratory solvents and buffers in routine use while routing flow to minimize backpressure in service and holds its seal true run after run. 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

• Mechanical strength keeps the matrix intact under vacuum or pressure
• Pore structure integrity holds through autoclave cycles up to 126°C
• DNA and RNA pass through with negligible adsorptive loss
• High flow rate pairs with a low extractable background
• Non-hydrogen-bonding surface avoids the polar adsorption nylon's amide backbone causes

Housing Characteristics

• Medical-grade polypropylene with broad chemical compatibility
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.

• Life Science Prep - Speeds processing of viscous biological solutions, improving laboratory workflow efficiency during busy sample prep days.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• Serum Filtration - Clarifies serum and plasma samples quickly while retaining critical proteins needed for accurate downstream analytical testing.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• 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.
