摘要

The incubator comprises two incubating rotors and a transfer device comprising the shuttle disposed above the rotors. The shuttle has an aperture sufficiently large as to receive, but not retain by friction, the vessel, the shuttle being free of a gripper that grips the vessel prior to raising it from the rotor or ungrips the raised vessel after it is within the unoccupied station of the other rotor. A first device linearly moves the shuttle so as to cause it and the aperture to traverse in a straight line from one of the rotors to the other. The incubator also has a first pusher member, and a second device for moving the pusher member into the one rotor into contact with a vessel in the one rotor, and for raising the contacted vessel out of its station in the one rotor into the shuttle. The pusher member and the one rotor station are sized so as to hold a raised vessel within the shuttle aperture until the shuttle has started to move away from the one rotor. A guide surface under the shuttle is constructed to retain the raised vessel in the aperture until a station in the other rotor is reached, so that alignment of the shuttle aperture with an unoccupied station of the other rotor is sufficient to cause the raised vessel to fall out of the aperture into the unoccupied station.
