Each rotor bucket will hold a centrifuge tube having a nominal fluid capacity of 5 ml; the buckets are sealed during operation by an O-ring and an aluminum bucket cap. The buckets attach to the rotor body, each at its own numbered position. During a centrifuge run, they swing out horizontally and return to a vertical position during deceleration. A disc with alternative black and reflective segments attached to the bottom of the rotor provides overspeed protection.
