ABSTRACT:
A centrifuge rotor having a balancing ring integrally formed with and raised from the upper surface thereof is manufactured by removing material from the ring to balance the rotor in the upper plane. The balancing ring is on the same radius as the rotor tube cavities and of width less than the diameter of said cavities such that the ring, when the tube cavities are drilled, is broken into segments of precisely known area which make the amount of material to be removed to balance the rotor readily determinable.
