Tisch Scientific PTFE Syringe Filters, 3 µm, 25 mm, 100/Pk - SPEC18140

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. PTFE filters aggressive organic solvents without swelling or breakdown while staying chemically inert against solvents, acids, and alkalis in service and blocks aqueous ingress in vent applications. Polypropylene construction holds extractable contribution low for sensitive analyses while sustaining efficient flow on viscous samples and prevents sample bypass under rated operating pressure. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Rigid polypropylene body holds its shape under manual filtration pressure
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Resists aqueous acids, bases, and alcohols in routine sample prep

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 from reaction mixtures and crude extracts through final analysis. Contact Tisch Scientific for technical guidance on selecting the right filtration product for your specific application requirements.
