PES Syringe Filters, 0.45um, 4mm, Luer-Lok/Luer Slip, Nonsterile, 200/Pk
Tisch SKU: SF17513

Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.45 µm, 4 mm, 200/Pk - SF17513

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Naturally hydrophilic PES wets on contact with aqueous samples and tolerates aqueous buffers, aliphatic alcohols, and glycols. Polypropylene construction maintains housing integrity through the filtration run while contributing minimal extractables to the filtrate and resists degradation from routine sample matrices. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

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

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path
• Rigid polypropylene body holds its shape under manual filtration pressure

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.
