Abstract: A bioreactor for suspension cells is provided. The bioreactor for suspension cells may comprise: a frame unit; a driving unit mounted on the frame unit, and a cell culture unit including a housing having an inner space filled with a medium containing suspension cells, and a plurality of supports disposed in multiple stages in the inner space to be spaced at intervals from each other, the cell culture unit having one end axially coupled to the driving unit.

Abstract: The present disclosure relates to a differential power horizontal-vertical switchable actuator module, the differential power horizontal-vertical switchable actuator module including: an actuator which rotates a horizontal drive shaft formed in the horizontal direction as a whole; a first gearbox which is connected to one side end of the horizontal drive shaft and transfers rotational power from the one side of the horizontal drive shaft by switching the direction to a first vertical rotation shaft that is in the vertical direction as a whole; and a second gearbox which is connected to the other side end of the horizontal drive shaft and transfers rotational power from the other side of the horizontal drive shaft by switching the direction to a second vertical rotation shaft that is in the vertical direction as a whole.
