PTFE Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF14475

Tisch Scientific PTFE Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF14475

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. PTFE delivers absolute particle cutoff at the rated pore size and blocks aqueous ingress in vent applications. Polypropylene construction resists chemical degradation from routine sample matrices while preventing sample bypass under rated operating pressure and maintains a low-dead-volume internal flow path. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

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

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

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.
