Tisch Scientific PTFE Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SPEC18137

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The PTFE membrane withstands aggressive organics that degrade other media while filtering aggressive organic solvents without breakdown and delivers sterilizing-grade gas and vent filtration. The PP housing stays inert across common laboratory solvents and buffers in routine use while routing flow to minimize backpressure in service and keeps the fluid path low in extractable contamination. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Filters aggressive organic solvents without swelling or breakdown
• Low extractables keep the chromatographic background clean
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Rigid polypropylene body holds its shape under manual filtration pressure
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Reliable solvent prefiltration clears particulates from your organic samples so your downstream method starts with a clean sample. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
