PTFE Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
Tisch SKU: SF14467

Tisch Scientific PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - SF14467

Tisch Scientific works with established filtration manufacturers to ensure reliable quality and performance. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Hydrophobic PTFE repels water while passing gases and solvents freely while suiting solvent filtration where other membranes fail and stays chemically inert against solvents, acids, and alkalis. Polypropylene construction holds extractable contribution low for sensitive analyses and resists degradation from routine sample matrices. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• 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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Reliable solvent prefiltration clears particulates from your organic samples so your downstream method starts with a clean sample.

• Aggressive Solvent Clarification - Filters THF, DMF, DMSO, and chloroform without membrane degradation in small-volume applications
• HPLC Sample Preparation - Removes particulates from samples in organic mobile phases to protect chromatography columns from fouling
• Strong Acid Filtration - Safely processes concentrated HCl, H2SO4, and HNO3 while maintaining membrane integrity in small volumes
• Protein Precipitation Clarification - Removes precipitates after TCA or organic solvent precipitation in analytical sample preparation
• Air and Gas Venting - Hydrophobic barrier prevents liquid intrusion in gas transfer lines and pressure equalization applications
• Pharmaceutical Sample Preparation - Prepares small-volume samples for dissolution testing in aggressive organic media and solvents
