Abstract
A solid mass rotor for centrifuges of the type supporting sample containers in cells which are radially positioned apertures in the rotor body features a cross-sectional shape which is relieved by a plurality of apertures, a first subset of which defines cells and a second subset of which defines relief zones. The solid mass of the rotor disposed between the cells and the relief zones defines a plurality of spokes extending from a radially central spin axis. The relief zones reduce the mass and overall moment of inertia of the rotor, while maintaining the strength and high speed capability associated with solid mass rotors.
