ABSTRACT:
A rotor adapted for use in a nonevacuated chamber has a liquid containment annulus having a capacity V.sub.C. The rotor also has a predetermined number N of liquid-capturing holes, each hole being sized and inclined such that it is able to capture therein a predetermined volume V.sub.H of liquid that may escape from a container while the rotor is rotating. At least some portion of the mouth of each hole lies radially outboard of a circular locus defined by corresponding points on each of a plurality M of container-receiving cavities in the rotor. The number N of holes and the volume V.sub.H of each hole satisfies the relationship:
