Pall
Acro Disc Syringe Filters w/ Ion Chromatography (IC) Supor Membrane - 0.45um, 13mm, 1000/Pk SKU: 4685

Polyethersulfone (PES) Syringe Filters, 0.45µm, 13mm - 4685

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. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

• 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
• 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
• High-Throughput Sterile Filtration - Processes large volumes of biological fluids significantly faster than standard PES to reduce processing time
