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

Polyethersulfone (PES) Syringe Filters, 5µm, 32mm - 4650

Engineered for speed and recovery, the Supor® Syringe Filters processes buffers and tissue culture media significantly faster than standard PES devices. Central to this high-throughput capability is the Supor® PES membrane, optimized with an asymmetric pore structure to deliver superior flow rates. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

Hydrophilic

• 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
