Acro Disc Syringe Filters w/ Supor Membrane - 0.2um, 25mm, Minispike Outlet, 1000/Pk
Pall SKU: 4783

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - 4783

Quality controls spanning raw membrane casting through final device integrity testing ensure consistent performance across Pall production lots. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. PES provides sterile-grade retention at the rated sub-micron pore size and accepts water-based reagents without preconditioning. The PP housing stays inert across common laboratory solvents and buffers in routine use while sustaining efficient flow on viscous samples and prevents sample bypass under rated operating pressure. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Stable across the full pH 1 to 14 operating range
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Low protein binding preserves dilute analytes for maximum recovery
• Absolute pore size rating gives consistent results across protocols
• Sterile-grade retention at sub-micron pore sizes

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Resists stress cracking from aqueous salt and buffer solutions
• Low extractable contribution protects sensitive downstream analyses

Sample clarification before injection is the cheapest insurance your chromatography system has. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.

• 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
• 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
