Abstract: A multiple bio-reactor device comprising a plurality of reactor segments, wherein a reaction vessel and at least one supply vessel can be secured to each reactor segment in a medium-tight suspended manner. A plurality of processing stations is provided in order to carry out predetermined processing steps with respect to the reaction vessel and/or supply vessels of each reactor segment, wherein an actuator is provided, in order to bring each reactor segment to a respective processing station or vice-versa. A respective reactor segment comprises a sterilizable domain that encompasses at least the reaction vessel and part of the reaction segment located thereabove.
