A robot hand includes a pair of bits and holds a microtube by causing the pair of bits to perform an opening-closing operation. The pair of bits has a lug that comes into contact with an outer peripheral surface of a container body or a cap portion of the microtube, and a rectangular recess in which parts of the cap portion and a flange of the microtube are inserted while the lug is in contact with an outer peripheral surface of the microtube. The rectangular recess includes surfaces between which the cap portion and the flange are disposed. The pair of bits is closed while a corner of the rectangular recess is in contact with the outer peripheral surface of the container body to retain the microtube in an orientation different from that in the state in which the cap portion is inserted in the rectangular recess. |
