PES Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
Tisch SKU: SF14501

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

Tisch Scientific customer service specialists focus on laboratory products and can help source the right solution for specific applications. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. PES stays stable across the full pH 1 to 14 range and draws aqueous samples through without pre-wetting. The polypropylene housing holds a reliable seal against the membrane edge while holding extractables low for sensitive analyses and routes flow to minimize backpressure in service. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• High flow rate with low extractable background for clean preparations
• Absolute pore size rating gives consistent results across protocols
• Stable across the full pH 1 to 14 operating range
• Low protein binding preserves dilute analytes for maximum recovery

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Rigid polypropylene body holds its shape under manual filtration pressure
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run.
