Tisch SKU: SPEC18103

Tisch Scientific Polyethersulfone (PES) Syringe Filters, 3 µm, 25 mm, 100/Pk - SPEC18103

Tisch Scientific keeps ordering simple, turning quotes and questions around quickly. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. PES accepts water-based reagents without surfactant preconditioning and handles strong bases across a broad aqueous range. The polypropylene housing contributes minimal extractables to the filtrate while maintaining a low-dead-volume internal flow path and holds a reliable seal against the membrane edge. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Thermal-bonded construction keeps adhesives out of the fluid path
• Stable across the full aqueous pH range in routine sample work
• Tough polypropylene body tolerates repeated handling at the bench

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 across your HPLC and UHPLC methods.
