Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.8um, 25mm, 50/Pk
Pall SKU: 4618

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.8 µm, 25 mm, 50/Pk - 4618

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Naturally hydrophilic PES wets on contact with aqueous samples while keeping protein adsorption low across the run and stays stable across the pH 1 to 14 range. The PP housing sustains efficient flow on viscous samples and stays inert across common laboratory solvents. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Stable across the full pH 1 to 14 operating range
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• 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

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Resists stress cracking from aqueous salt and buffer solutions
• Medical-grade polypropylene with broad chemical compatibility
• Tough polypropylene body tolerates repeated handling at the bench

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

• Buffer Filtration - Ensures particulate-free buffers for critical downstream processes and instrumentation to prevent costly system downtime
• Viscous Biologicals - Maintains flow rates even when filtering protein-rich or slightly viscous biological fluids that would clog other filters
• 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
• 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
