Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.8/0.2um, 32mm, 50/Pk
Pall SKU: 4658

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 32 mm, 50/Pk - 4658

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. PES accepts water-based reagents without surfactant preconditioning and handles strong bases across a broad aqueous range. The polypropylene housing contributes minimal extractables to the filtrate while maintaining housing integrity through the filtration run and resists aqueous acids, bases, and alcohols. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Low protein binding preserves dilute analytes for maximum recovery
• Sterile-grade retention at sub-micron pore sizes
• High flow rate with low extractable background for clean preparations
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification keeps your sample preparation moving from the first sample of the day through the last.

• Media Preparation - Sterilizes tissue culture media with minimal protein loss, ensuring optimal cell growth and viability in sensitive cultures
• Time-Sensitive Prep - Accelerates filtration workflows where speed is critical to preserving sample integrity and preventing biological degradation
• Viscous Biologicals - Maintains flow rates even when filtering protein-rich or slightly viscous biological fluids that would clog other filters
• High-Throughput Sterile Filtration - Processes large volumes of biological fluids significantly faster than standard PES to reduce processing time
• Buffer Filtration - Ensures particulate-free buffers for critical downstream processes and instrumentation to prevent costly system downtime
• Biologicals - Maximizes recovery of high-value proteins and therapeutics during sterile filtration steps, protecting yield in production runs
