Stirred Cells

Units for processing from 3 to 400 mL

Amicon stirred cells provide high flow rates with solutions up to 10% macrosolute concentration. Capable of rapid concentration, or salt removal followed by concentration in the same unit. Complete product recoveries can generally be achieved using the diafiltration set-up as illustrated on this page.

Gentle magnetic stirring minimizes concentration polarization and shear denaturation. All stirred cells can be autoclaved.

Diafiltration set-up and operation with Amicon selector valve, stirred cell and accessory reservoir.
1 - Ultrafiltrate, 2 - Ultrafiltration equipment, 3 - Pressure supply, 4 - Selector valve, 5 - Inlet, 6 - Outlet, 7 - Feed liquid, 8 - Reservoir
