PTFE Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF14473

Tisch Scientific PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - SF14473

Tisch Scientific works with established filtration manufacturers to ensure reliable quality and performance. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The PTFE membrane clarifies solvent streams at the rated pore size and repels water while passing gases and solvents freely. Polypropylene construction maintains housing integrity through the filtration run while resisting degradation from routine sample matrices and sustains efficient flow on viscous samples. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Tough polypropylene body tolerates repeated handling at the bench
• Optimized internal geometry minimizes backpressure in service
• Resists stress cracking from aqueous salt and buffer solutions

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.

• Aggressive Solvent Clarification - Removes particles from THF, DMF, and DMSO samples where contamination-free handling is required
• HPLC Sample Preparation - Removes particulates from samples in organic mobile phases, protecting chromatography columns from contamination
• Strong Acid Handling - Filters concentrated HCl, H2SO4, and HNO3 in analytical workflows requiring chemical resistance and particle removal
• Protein Precipitation Cleanup - Clarifies samples after TCA or organic solvent precipitation in proteomics and biochemistry sample preparation
• Tissue Culture Solvent Processing - Filters organic solvents used in fixation and extraction protocols where contamination-free handling matters
• Pharmaceutical Dissolution Testing - Prepares samples for dissolution testing in aggressive media requiring chemical resistance and clarification
