Tisch Scientific PTFE Syringe Filters, 0.22 µm, 33 mm, 100/Pk - SF14476

Tisch Scientific customer service specialists focus on laboratory products and can help source the right solution for specific applications. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. PTFE stays chemically inert against aggressive solvents, strong acids, and alkalis in service while suiting gas, vent, and solvent-stream filtration and suits solvent filtration where other membranes fail. Polypropylene construction holds extractable contribution low for sensitive analyses while preventing sample bypass under rated operating pressure and routes flow to minimize backpressure in service. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Low extractables keep the chromatographic background clean
• Stable across a wide operating temperature range for demanding methods
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure

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 from organic mobile-phase prep through reagent clarification. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.
