Abstract

A bioreactor has a stirrer shaft that is driveable by a drive and on which a stirrer element is positioned. The position of the stirrer element is determined by a stirrer installation aid. The stirrer installation aid has a free end with an abutment surface on which the free end of the stirrer element abuts. The stirrer installation aid is designed as a sleeve that comprises a slot extending between the axial ends of the sleeve. The slot is delimited by opposite flanks of a wall, and the sleeve is placed on the stirrer shaft. The stirrer installation aid can be pulled off laterally from the stirrer shaft. A method for installing the stirrer element on the stirrer shaft arranged in the bioreactor also is provided.
