Tisch SKU: SF18099

Tisch Scientific PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - SF18099

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. PTFE delivers absolute particle cutoff at the rated pore size while combining aqueous wetting with solvent resistance and filters aggressive organic solvents without breakdown. The PP housing prevents sample bypass under rated operating pressure while sustaining efficient flow on viscous samples and contributes minimal extractables to the filtrate. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Surface-treated for direct aqueous wetting without alcohol pre-wetting
• Stable across a wide operating temperature range for demanding methods
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path before they reach the column inlet or detector.
