Tisch SKU: SF17504

Tisch Scientific PTFE Syringe Filters, 0.22 µm, 4 mm, 200/Pk - SF17504

Tisch Scientific works with established filtration manufacturers to ensure reliable quality and performance. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Chemically inert PTFE achieves sterile-grade retention in gas and vent service and resists attack from the harshest process chemistries. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while routing flow to minimize backpressure in service and contributes minimal extractables to the filtrate. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Absolute pore size rating gives consistent results across protocols
• Stable across a wide operating temperature range for demanding methods
• Low extractables keep the chromatographic background clean
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run.
