Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.45 µm, 30 mm, 100/Pk - SF15609

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Naturally hydrophilic PES wets on contact with aqueous samples while handling strong bases across a broad aqueous range and keeps protein adsorption low across the run. Polypropylene construction resists chemical degradation from routine sample matrices while maintaining a low-dead-volume internal flow path and holds a reliable seal against the membrane edge. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• High flow rate with low extractable background for clean preparations
• 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
• Stable across the full pH 1 to 14 operating range

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Resists stress cracking from aqueous salt and buffer solutions
• Rigid polypropylene body holds its shape under manual filtration pressure
• Medical-grade polypropylene with broad chemical compatibility

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.
