Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SPEC18105

Tisch Scientific keeps ordering simple, turning quotes and questions around quickly. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Low-binding PES preserves dilute proteins and analytes in the filtrate while delivering sharp particle cutoff at the rated pore size and tolerates aqueous buffers, aliphatic alcohols, and glycols. The PP housing keeps the fluid path low in extractable contamination while routing flow to minimize backpressure in service and maintains housing integrity through the filtration run. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• 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
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Stable across the full aqueous pH range in routine sample work
• Resists aqueous acids, bases, and alcohols in routine sample prep

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.
