Pall Acrodisc Water-Wettable PTFE Syringe Filters, 0.45 µm, 25 mm, 200/Pk - AP-4919

Pall's engineering and quality infrastructure extends from its process-scale filtration systems to its laboratory devices. Across analytical workflows, the syringe filter is where particulates leave the sample stream. The hydrophilic PTFE membrane suits aqueous and solvent-based samples alike while staying chemically inert against aggressive solvents and acids in service and holds a sharp particle cutoff at the rated pore size. The PP housing sustains efficient flow on viscous samples while keeping the fluid path low in extractable contamination and stays inert across common laboratory solvents. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Water-wettable surface wets directly with both aqueous and organic samples
• Absolute pore-size rating gives consistent retention across protocols
• Chemically inert to aggressive organic solvents, strong acids, and alkalis
• Low protein binding preserves dilute analytes for maximum recovery
• Universal compatibility across aqueous buffers and organic solvents

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• 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

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
