The present invention provides an agitation device and a gear train. The agitation device includes: at least one gear; at least one agitation tube; and at least one joining unit which joins the gear with the agitation tube. The gear, the joining unit, and an agitation portion are hollow. The gear rotates the agitation tube through the joining unit. Agitation is performed by using the gear and the agitation tube arranged in the agitation device. Not only the maximum flux per area can be obtained but also problems related to cross-contamination can be reduced. In addition, in the gear train, collimation of the agitation device can be increased by a certain hollow gear, arranged in the gear train, and an extended hollow bearing train. |
