Abstract
An apparatus and method of stirring cells in liquid culture media is provided. Baffles are mounted along the interior wall of the container and a hump is positioned on the center of the bottom surface of the container. A stirring apparatus is positioned inside the container. The blades of the stirring apparatus are angled outward toward the bottom of the container. The bottom edge of the blades extend closer to the bottom surface of the container then the apex of the hump. The liquid in the container is at a level below the top of the blades such that the blades are moved through the surface of the liquid. A magnetic bar is attached to the shaft and is driven by an external rotating magnetic bar.
