Abstract

A stirrer for a bioreactor has first and second opposed mountings fastened to the inner surfaces of opposite walls of the bioreactor and disposed along a common rotational axis. A first arm has an end connected to the first mounting for rotation about the rotational axis and for pivoting about a first pivot axis that is transverse to the rotational axis. A second arm has an end connected to the second mounting for rotation about the rotational axis and for pivoting about a second pivot axis that is transverse to the rotational axis. Ends of the arms are coupled for pivoting about at least one additional pivot axis that is transverse to the rotational axis.
