Tisch SKU: SF18053

Tisch Scientific PTFE Syringe Filters, 1 µm, 25 mm, 100/Pk - SF18053

Tisch Scientific welcomes bulk and blanket orders with volume discounts. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Hydrophilic PTFE accepts aqueous samples on contact without alcohol pre-wetting while clarifying solvent streams at the rated pore size and handles concentrated acids and bases. The PP housing keeps the fluid path low in extractable contamination and maintains a low-dead-volume internal flow path. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean
• Stable across a wide operating temperature range for demanding methods
• Surface-treated for direct aqueous wetting without alcohol pre-wetting

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility
• Stable across the full aqueous pH range in routine sample work
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
