Pall Acrodisc Water-Wettable PTFE Syringe Filters, 0.45 µm, 25 mm, 1000/Pk - AP-4918

Pall Corporation brings decades of fluid management expertise to laboratory-scale filtration challenges. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Absolute-rated hydrophilic PTFE holds a sharp particle cutoff at the rated pore size while staying chemically inert against aggressive solvents and acids in service and minimizes analyte loss to the surface. Polypropylene construction maintains housing integrity through the filtration run 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

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

Housing Specifications

• Stable across the full aqueous pH range in routine sample work
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Tough polypropylene body tolerates repeated handling at the bench

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
