Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF14501

Tisch Scientific makes the ordering process straightforward, turning around requests for pricing and product information fast. Individually packaged and pre-tested, a syringe filter needs no functional check before use the way a shared reusable holder does. The PES membrane loads aqueous buffers with zero pre-wetting delay while pairing fast flow with reduced protein adsorption and tolerates aliphatic alcohols, glycols, and aqueous buffers. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane while standing firm against aqueous acids, bases, and alcohols during regular handling and maintains a low-dead-volume internal flow path. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Membrane Characteristics

• Antibody and protein samples pass through PES with minimal adsorptive loss
• Ionic extractables from the membrane stay very low
• DNA and RNA pass through with negligible adsorptive loss
• Chemical breadth spans alcohols, glycols, and aqueous buffers
• Sulfone backbone's hydrolytic stability tolerates repeated autoclave steam sterilization cycles

Housing Characteristics

• Medical-grade polypropylene with broad chemical compatibility
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Optimized internal geometry minimizes backpressure in service
• Housing rated for reliable filtration under syringe-applied backpressure at its maximum operating 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.

Hydrophilic

• 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.
• Life Science Prep - Speeds processing of viscous biological solutions, improving laboratory workflow efficiency during busy sample prep days.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
