ABSTRACT:
An identification means placed adjacent the test tube cavities in a centrifuge rotor. The identification means utilizes recessed or indented indicia which are positioned on a circular ring raised above the generally flat top surface of the rotor. The identification indicia are used for identifying or labeling each of the test tube cavities in the rotor. The raised nature of the ring eliminates the possible establishment of weak points or areas in the top surface of the rotor during centrifugation.
