Tisch Scientific PTFE Syringe Filters, 0.45 µm, 30 mm, 100/Pk - SF16000

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. The PTFE membrane withstands aggressive organics that degrade other media while suiting gas, vent, and solvent-stream filtration and clarifies solvent streams at the rated pore size. The PP housing keeps the fluid path low in extractable contamination while sustaining efficient flow on viscous samples and prevents sample bypass under rated operating pressure. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis
• 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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

• Aggressive solvents - High-volume clarification of THF, DMF, DMSO, chloroform, acetonitrile for synthesis scale-up and purification
• HPLC sample prep - Particulate removal from 50-120ml samples in organic mobile phases, preventing column fouling and backpressure issues
• Strong acid filtration - Safe handling of concentrated HCl, H2SO4, HNO3, TFA for method development and large-batch trace analysis
• Protein precipitation - Clarification after TCA, methanol, or acetonitrile precipitation in proteomics and bioanalytical sample preparation
• Environmental testing - Filtration of soil extracts, sediment samples, and industrial waste streams containing organic solvents
• Pharmaceutical development - Sample preparation for dissolution testing in aggressive media and organic solvent extraction procedures
