A determination mechanism which obtains information about the weight of the specimen housed in the specimen container is arranged on a conveyor line for connecting between a loading module and an automatic centrifugal unit, the specimens are held without being installed at an adaptor until the number of the specimens which can be subjected to a centrifugal processing at once by the automatic centrifugal unit arrives, and the specimens are installed after the arrival in an order from a heavier specimen at the adaptors to be paired, which are installed at the symmetric positions to each other across the rotation central axis. Also, the specimen is installed at the gravity-center position of the adaptor first, and the subsequent specimens are installed from the inner side at the point-symmetric positions to each other across the gravity-center position.

The invention relates to a centrifuge rotor with two centrifuge rotor parts. In the assembled state, the centrifuge rotor parts delimit an inner chamber in which a product to be centrifuged can be arranged. According to various embodiments, the centrifuge rotor parts are connected to each other or can be connected to each other by a locking device. The locking device is actuated and/or is biased towards a locking position by means of a centrifugal force as a result of the rotation of the centrifuge rotor.

There is provided a centrifuge including a rotor including a weight movement mechanism that supports a solid adjustment weight to be movable along a radial direction on an opposite side in the radial direction from an end portion of the rotor by which a specimen to be centrifuged is held; and a center-of-gravity adjustment unit disposed at a position away from the rotor to be connectable to the rotor, and including a weight drive mechanism connected to the weight movement mechanism to move the adjustment weight on the rotor. The center-of-gravity adjustment unit calculates a movement amount or a movement position of the adjustment weight according to an input weight of a container storing the specimen, and moves the adjustment weight.
