PES Syringe Filters, 1.0um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF18271

Tisch Scientific Polyethersulfone (PES) Syringe Filters, 1 µm, 25 mm, 100/Pk - SF18271

Tisch Scientific keeps ordering simple, turning quotes and questions around quickly. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. The PES matrix tolerates aqueous buffers, aliphatic alcohols, and glycols in routine use and delivers sharp particle cutoff at the rated pore size. Polypropylene construction resists chemical degradation from routine sample matrices while preventing sample bypass under rated operating pressure and maintains a low-dead-volume internal flow path. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• High flow rate with low extractable background for clean preparations
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Low protein binding preserves dilute analytes for maximum recovery
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists stress cracking from aqueous salt and buffer solutions
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
