Abstract
A dilutor/dispenser system wherein a marker, e.g., an air bubble, is introduced at the probe inlet prior to each aspiration cycle, so as to be displaced along the probe system during such cycle. The location of the marker is detected at the end of the aspiration cycle, to indicate whether an appropriate liquid volume has been aspirated. The aspirated liquid, along with the marker and a predetermined volume of diluent, is subsequently dispensed. An alarm may be activated, if an improper volume has been aspirated.
