  • Biological sample processing apparatus that selects the personality type of the apparatus
    Patent number: 7891549
    Abstract: A biological sample processing apparatus having a central processing unit, a display in communication with the central processing unit and a selector for selecting a personality type of the apparatus, the selector being in communication with the central processing apparatus. The selection of a personality type prompts the central processing unit to cause the display to show a list of preprogrammed protocols for biological sample processing that correspond to the selected personality type.
    Type: Grant

  • Apparatus and method for use in magnetic separation of magnetically attractable particles in a liquid
    Publication number: 20020070173
    Abstract: An apparatus and method for use in magnetic separation of magnetically attractable particles suspended in a liquid. The apparatus includes a magnetic separator plate having a plurality of channels, one for each column of wells of a multi-well assay plate which is received by the magnetic separator plate. A plurality of magnets are positioned in each channel so that when the magnetic separator plate receives the multi-well assay plate, the magnets attract the magnetically attractable particles to create a pellet of material of a substance of interest on a side wall within each associated well.
