Abstract
Disclosed is a method of determining a volume of liquid in a sample tube, comprising the steps of capturing an image of the sample tube, determining a first region of interest within the sample tube based upon pre-stored information concerning dimensional properties of the sample tube, scanning the first region of interest to detect the position of a meniscus indicative of an upper extent of the liquid, and using said meniscus position together with certain pre-stored properties of the sample tube to determine a volume of liquid in the tube, and outputting said volume. Also disclosed is an apparatus for performing the method.
