PTFE Syringe Filters, 5.0um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
Tisch SKU: SF17400

Tisch Scientific PTFE Syringe Filters, 5 µm, 25 mm, 100/Pk - SF17400

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. The PTFE matrix handles concentrated acids and bases across demanding methods and repels water while passing gases and solvents freely. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while sustaining efficient flow on viscous samples 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

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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Rigid polypropylene body holds its shape under manual filtration pressure
• Thermal-bonded construction keeps adhesives out of the fluid path

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 so your filter holds its integrity through the run.

• Coarse prefiltration - Removal of large particulates, precipitates, and suspended solids from reaction mixtures and crude extracts
• Sample clarification - Initial filtration of heavily contaminated samples before fine filtration, protecting downstream 0.22 or 0.45µm filters
• Aggressive solvents - High-flow prefiltration of THF, DMF, DMSO, chloroform, and acetonitrile containing visible particulates
• Crystal removal - Rapid separation of crystallized products from mother liquors in organic synthesis and recrystallization procedures
• Catalyst recovery - Removal of heterogeneous catalysts, activated carbon, and solid-phase reagents from organic reaction mixtures
• Environmental samples - Prefiltration of soil extracts, sediment samples, and industrial waste streams before analytical testing
