PES Syringe Filters, 0.22 um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
Tisch SKU: SF14499

Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF14499

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. Across analytical workflows, the syringe filter is where particulates leave the sample stream. The PES membrane draws aqueous buffers through without pre-wetting while tolerating aqueous buffers, aliphatic alcohols, and glycols in routine use and preserves dilute proteins and analytes in the filtrate. The PP housing sustains efficient flow on viscous samples while keeping the fluid path low in extractable contamination and holds a reliable seal against the membrane edge. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Absolute pore size rating gives consistent results across protocols
• Sterile-grade retention at sub-micron pore sizes
• Low protein binding preserves dilute analytes for maximum recovery

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Rigid polypropylene body holds its shape under manual filtration pressure
• Low extractable contribution protects sensitive downstream analyses
• Tough polypropylene body tolerates repeated handling at the bench

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
