Tisch Scientific PTFE Syringe Filters, 3 µm, 33 mm, 100/Pk - SF17044

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The PTFE membrane clarifies solvent streams at the rated pore size while suiting solvent filtration where other membranes fail and withstands aggressive organics that degrade other media. The polypropylene housing holds a reliable seal against the membrane edge while holding extractables low for sensitive analyses and resists degradation from routine sample matrices. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Low extractables keep the chromatographic background clean
• Stable across a wide operating temperature range for demanding methods
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols
• Filters aggressive organic solvents without swelling or breakdown

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Optimized internal geometry minimizes backpressure in service
• 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. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.
