Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.2um, 32mm, 50/Pk
Pall SKU: 4652

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 32 mm, 50/Pk - 4652

Pall's engineering and quality infrastructure extends from its process-scale filtration systems to its laboratory devices. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Naturally hydrophilic PES wets on contact with aqueous samples and tolerates aqueous buffers, aliphatic alcohols, and glycols. Polypropylene construction resists chemical degradation from routine sample matrices and keeps the fluid path low in extractable contamination. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

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

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Stable across the full aqueous pH range in routine sample work
• Optimized internal geometry minimizes backpressure in service

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.

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