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.
A method for controlling the motion of a rotor body fragment after a centrifuge rotor failure has occurred within a centrifuge assembly which comprises a centrifuge chamber, a centrifuge lid enclosing said centrifuge chamber, and a rotor body mounted for rotation within said centrifuge chamber, said method comprising the step of:
A centrifuge assembly comprising a non-rotating centrifuge chamber, a centrifuge lid for providing access to and enclosing said centrifuge chamber, and a rotor body mounted for rotation within said centrifuge chamber, wherein a lower portion of said centrifuge chamber contains an outward perturbation radially adjacent to an outermost point of said rotor body to cause a moment of a rotor body fragment, which is a result of a centrifuge rotor failure, to move along said centrifuge chamber away from said centrifuge lid.
A centrifuge assembly which comprises a centrifuge chamber, a guard ring disposed about the outside of said centrifuge chamber, a centrifuge lid enclosing said centrifuge chamber, and a rotor body mounted for rotation within said centrifuge chamber, wherein said guard ring is sloped away from a lower portion of said centrifuge chamber to cause the moment of a rotor body fragment, which is the result of a centrifuge rotor failure, to move along said centrifuge chamber and said guard ring away from said centrifuge lid.
