  • Method and device for automatic chemical analysis
    Patent number: 5882596
    Abstract: The present invention provides a vessel shuttle which can be used, for example, for moving reaction vessels to or from an assay resource station in an automated chemical analyzer. The vessel shuttle has a plurality of movable plates including first and second vessel carrying plates adapted to move cooperatively with respect to one another to advance a vessel stepwise along a linear path without net motion of the first and second vessel carrying plates as the vessel is advanced one step. In a preferred embodiment, the first and second vessel carrying plates each comprise a plurality of fingers defining recesses for receiving vessels and the first vessel carrying plate is adapted to move in a direction substantially perpendicular to the vessels' linear path and the second vessel carrying plate is adapted to move rectilinearly both generally parallel to and generally perpendicular to that linear path.
    Type: Grant
