Pall ValuPrep PTFE Syringe Filters, 0.45 µm, 13 mm, 1000/Pk - 6614563

Pall Corporation brings decades of fluid management expertise to laboratory-scale filtration challenges. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The treated PTFE membrane combines aqueous wetting with broad solvent resistance while handling concentrated acids and strong bases and stays chemically inert against solvents, acids, and alkalis. The PP housing prevents sample bypass under rated operating pressure 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

• Low extractables keep the chromatographic background clean
• Filters aggressive organic solvents without swelling or breakdown
• Surface-treated for direct aqueous wetting without alcohol pre-wetting
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Tough polypropylene body tolerates repeated handling at the bench
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Stable across the full aqueous pH range in routine sample work

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Reliable particulate removal protects your instruments and your data so column life and baseline stability stay predictable.
