PES Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
Tisch SKU: SF14498

Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - SF14498

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. PES holds consistent absolute retention at the rated pore size while preserving dilute proteins and analytes in the filtrate 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 holds extractables low for sensitive analyses. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

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

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses
• Resists stress cracking from aqueous salt and buffer solutions
• Thermal-bonded construction keeps adhesives out of the fluid path

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
