Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 5um, 32mm, 50/Pk
Pall SKU: 4650

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 5 µm, 32 mm, 50/Pk - 4650

Pall Corporation combines proprietary membrane technology with a housing platform validated for both manual and automated filtration workflows. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. PES minimizes protein binding to maximize sample and analyte recovery while handling strong bases across a broad aqueous range and clarifies particulates at the rated pore size. Polypropylene construction holds extractable contribution low for sensitive analyses while holding a reliable seal against the membrane edge 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

• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Low protein binding preserves dilute analytes for maximum recovery
• High flow rate with low extractable background for clean preparations
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• 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
• Rigid polypropylene body holds its shape under manual filtration pressure

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

• 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
• 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
• 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
