Tisch Scientific PTFE Syringe Filters, 3 µm, 13 mm, 100/Pk - SF18276

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. 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 while staying chemically inert against solvents, acids, and alkalis in service and handles concentrated acids and bases. Polypropylene construction holds extractable contribution low for sensitive analyses while resisting degradation from routine sample matrices and holds a reliable seal against the membrane edge. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Stable across a wide operating temperature range for demanding methods
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Low extractables keep the chromatographic background clean
• Filters aggressive organic solvents without swelling or breakdown
• Hydrophobic membrane repels water for gas, vent, and solvent filtration

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure

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 so your downstream method starts with a clean sample. Call on the Tisch Scientific team to standardize filtration products across your methods with volume pricing and documentation.
