Pall SKU: 4612

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 4612

Pall Corporation brings decades of fluid management expertise to laboratory-scale filtration challenges. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. PES minimizes protein binding to maximize sample and analyte recovery while providing sterile-grade retention at sub-micron pore sizes and wets on contact with aqueous buffers. Polypropylene construction maintains a low-dead-volume internal flow path and resists aqueous acids, bases, and alcohols. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Sterile-grade retention at sub-micron pore sizes
• Low protein binding preserves dilute analytes for maximum recovery
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• High flow rate with low extractable background for clean preparations
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Stable across the full aqueous pH range in routine sample work
• Optimized internal geometry minimizes backpressure in service
• Resists stress cracking from aqueous salt and buffer solutions

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.
