PTFE Syringe Filters, 0.22 um, 25mm, Double Luer Lock, PP Housing, Nonsterile, 100/Pk
Tisch SKU: SPEC16251

Tisch Scientific PTFE Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SPEC16251

Tisch Scientific works with established filtration manufacturers to ensure reliable quality and performance. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. The hydrophobic PTFE membrane provides bacterial retention in gas and vent streams while suiting gas, vent, and solvent-stream filtration and handles concentrated acids and bases. The PP housing sustains efficient flow on viscous samples and maintains housing integrity through the filtration run. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Tough polypropylene body tolerates repeated handling at the bench
• Rigid polypropylene body holds its shape under manual filtration pressure
• Optimized internal geometry minimizes backpressure in service

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Reliable solvent prefiltration clears particulates from your organic samples ahead of HPLC and UPLC injection.
