PTFE Syringe Filters, Hydrophilic, 0.45um, 13mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF18010

Tisch Scientific PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - SF18010

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. PTFE suits solvent and reagent filtration where other membranes fail while holding consistent absolute retention at the rated pore size and wets directly with aqueous samples. The polypropylene housing contributes minimal extractables to the filtrate and stays inert across common laboratory solvents. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• 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
• Surface-treated for direct aqueous wetting without alcohol pre-wetting

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Resists stress cracking from aqueous salt and buffer solutions
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.
