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.
