Abstract
Automated laboratory apparatus for determining the volume of liquid samples contained in the cavities of laboratory sample collectors, such as well trays or tube racks, the apparatus having an ultrasonic height measuring instrument and a processor for calculating the volume of liquid in a particular sample container from the measured height, the apparatus also having a robotic displacement mechanism that selectively positions an ultrasonic height measuring sensor above a select sample container in the well tray or tube rack for measuring the height of liquid in the container, comparing the measured height to the height of the bottom of an empty container and calculating the volume of liquid in that container.
