Tisch Scientific PTFE Syringe Filters, 0.45 µm, 17 mm, 100/Pk - SF15623

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The PTFE membrane clarifies solvent streams at the rated pore size while handling concentrated acids and strong bases and repels water while passing gases and solvents freely. The polypropylene housing routes flow to minimize backpressure in service while resisting aqueous acids, bases, and alcohols in routine use and prevents sample bypass under rated operating pressure. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Low extractables keep the chromatographic background clean
• Stable across a wide operating temperature range for demanding methods
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Filters aggressive organic solvents without swelling or breakdown

Housing Specifications

• Stable across the full aqueous pH range in routine sample work
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
