Acro Disc Syringe Filters w/ Ion Chromatography (IC) Supor Membrane - 0.45um, 25mm, 1000/Pk SKU: AP-4785

Polyethersulfone (PES) Syringe Filters, 0.45µm, 25mm - AP-4785

Engineered for speed and recovery, the Supor® Syringe Filters processes buffers and tissue culture media significantly faster than standard PES devices. Driving this biological efficiency is an ultra-low protein binding surface that minimizes the loss of active ingredients during sterile filtration. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

• Media Preparation - Sterilizes tissue culture media with minimal protein loss, ensuring optimal cell growth and viability in sensitive cultures
• 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
• High-Throughput Sterile Filtration - Processes large volumes of biological fluids significantly faster than standard PES to reduce processing time
• Biologicals - Maximizes recovery of high-value proteins and therapeutics during sterile filtration steps, protecting yield in production runs
• Viscous Biologicals - Maintains flow rates even when filtering protein-rich or slightly viscous biological fluids that would clog other filters
