A shell-type centrifuge rotor includes a body member having an upturned lip and a plate having a skirt portion attached to the body. The skirt portion has a groove therein that overlies the lip on the body. The groove defines a relatively high stress region of likely failure of the rotor. A seal is disposed in the groove, the seal extending between the plate and the lip,. Failure of the rotor in the vicinity of the groove in the skirt portion at a first operating speed defining an opening through which a portion of the seal may protrude. The protruding portion of the seal generates a force tending to lower the speed of the rotor below the first operating speed. The radially inner surface of the seal ring is inclined toward the axis of rotation. The radially inner boundary surface of the groove is parallel to or inclined radially inwardly toward the axis of rotation. <IMAGE> |
