ABSTRACT:
A method and apparatus which are capable of controlling the motion of a rotor body fragment after a rotor failure has occurred within a centrifuge assembly which comprises a rotor body, a centrifuge chamber and a centrifuge lid. The moment of the rotor body fragment can be controlled such that it moves along the centrifuge chamber away from the centrifuge lid by any of the following: (a) adjusting the center of gravity of the rotor such that it is below the strike point plane of the rotor; (b) adjusting the shape of the centrifuge chamber to conform to the rotor body shape; (c) sloping the guard ring such that the lower portion is furthest away from the centrifuge chamber; (d) varying the strength or stiffness of the guard ring or centrifuge chamber at or above the center of gravity of the rotor body fragment; and (e) adding a ring member to the top of the centrifuge rotor body.
