Abstract
A method for determining and correcting for the variations in height of a rotor as it wobbles when rotating past a particular critical circumferential position. The method comprises sensing a reference surface of each vessel in the rotor that is to be filled during the use of the rotor in an incubator, as a tare height of the vessel, so that the effect of the vertical run-out is known and corrected for by the computer. Air pressure is used to detect the reference surface, either from a vessel-wash probe connected to the source of air pressure, or a separate sensor probe.
