Tisch Scientific PTFE Syringe Filters, 3 µm, 25 mm, 100/Pk - SPEC16279

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. Hydrophobic PTFE repels water while passing gases and solvents freely while filtering aggressive organic solvents without breakdown and clarifies solvent streams at the rated pore size. The PP housing sustains efficient flow on viscous samples while maintaining housing integrity through the filtration run and resists degradation from routine sample matrices. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Stable across a wide operating temperature range for demanding methods
• Low extractables keep the chromatographic background clean
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Filters aggressive organic solvents without swelling or breakdown
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through final analysis. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
