Amicon^® Stirred Cell Selector Valve

The best in large-volume ultrafiltration just got better. Introducing the new Amicon® Stirred Cell. You’re an Amicon® Stirred Cell owner. You’re adept at finely separating macrosolutes in large-volume (50-400 mL) samples, and you depend on the precision of Amicon® devices. Or maybe you are an expert in membrane analysis, and you count on a device that lets you insert membranes of your choice. With your needs in mind, EMD Millipore has developed the new Amicon® Stirred Cell, providing the same gentle, high recovery of macrosolutes and thorough buffer exchange to which you’re well accustomed. It provides the same membrane flexibility and ability to monitor filtration progress.

The Amicon® Stirred Cell family of pressure-driven filtration devices provide an ideal solution for concentrating and buffer-exchanging large volumes of macrosolutes. These devices are available in multiple sizes to offer a wide range of processing volumes. Additionally, to accommodate expansion to even larger processing volumes, an external reservoir can be attached to any Amicon® Stirred Cell. Unlike ultrafiltration with tangential flow filtration (TFF) devices, which are manufactured with pre-sealed membranes, the Amicon® Stirred Cells use membrane discs, which are easily exchanged to match changing sample preparation needs.
