Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF14506

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. The PES matrix tolerates aqueous buffers, aliphatic alcohols, and glycols in routine use and draws aqueous samples through without pre-wetting. Polypropylene construction maintains a low-dead-volume internal flow path while maintaining housing integrity through the filtration run and stays inert across common laboratory solvents. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Sterile-grade retention at sub-micron pore sizes
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Low protein binding preserves dilute analytes for maximum recovery
• High flow rate with low extractable background for clean preparations
• Stable across the full pH 1 to 14 operating range

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Stable across the full aqueous pH range in routine sample work

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule.
