Abstract
A peripheral band is used as a load-containment device in a high-capacity, swinging bucket centrifuge rotor. The peripheral band is concavo-convex in radial cross-section such that the mid portion of the band is thinner than the edge portions to provide increased structural strength and reduced wind resistance. The rotor includes a hub and a shaped disc-like piece of sheet metal which forms the bottom of the rotor and interconnects the rotor hub with the peripheral band. The rotor bottom supports the band against gravity. The swinging buckets themselves are mounted on pivots secured to the band. In this manner, the available volume of the inside of the rotor cavity is increased.
