  • Patent number: 9222821
    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.

  • Patent number: 7450224
    Abstract: An apparatus and method are provided for determining boundaries between fractions in a fractionated sample. The method includes the steps of providing the fractionated sample in a receptacle, the receptacle having a transparent window, positioning the receptacle in a known position relative to datum means, capturing an image of the receptacle and datum means, and processing the image to determine the position of boundaries between the fractions in the sample relative to the datum means. An apparatus and method for extracting a selected fraction of a fractionated sample are also disclosed.
