Tisch Scientific PTFE Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SPEC17163

Tisch Scientific welcomes bulk and blanket orders with volume discounts. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Chemically inert PTFE resists attack from the harshest process chemistries and suits solvent filtration where other membranes fail. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use 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

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols
• Stable across a wide operating temperature range for demanding methods

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Medical-grade polypropylene with broad chemical compatibility

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. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
