Tisch Scientific PTFE Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF14474

Tisch Scientific welcomes bulk and blanket orders with volume discounts. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Chemically inert PTFE resists attack from the harshest process chemistries while achieving sterile-grade retention in gas and vent service and repels water while passing gases and solvents freely. Polypropylene construction maintains housing integrity through the filtration run while contributing minimal extractables to the filtrate and resists aqueous acids, bases, and alcohols. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Stable across a wide operating temperature range for demanding methods
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists stress cracking from aqueous salt and buffer solutions

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 ahead of HPLC and UPLC injection. Call on the Tisch Scientific team to standardize filtration products across your methods with volume pricing and documentation.
