Centrifuge rotor balancing bosses

摘要

Balancing bosses integrally forged in a centrifuge rotor. The plurality of balancing bosses in the rotor establish noncritical areas in the rotor for machining to accomplish the precise balancing necessary for high speed ultracentrifugation. The balancing bosses are located away from the high stress periphery of the rotor so that machining a portion of the bosses for balancing purposes will not degrade the integral strength of the rotor.
