ABSTRACT:
An automated multi-purpose analytical chemistry processing center and laboratory work station having a movable table for supporting microtiter plates and other fluid receptacles, a movable arm, and a modular mobile pod affixed for reciprocal movement along the arm. The work station combines into a single programmable system the capabilities for automation of a wide range of bioanalytical procedures including, not only sample pipetting, serial dilution, reagent additions, mixing, reaction timing and similar known manual procedures, but also programmable spectrophotometric measurements and other physical parameters, further processing based on these measurements and automatic data recording. The work station is adapted to transfer, dispense, and aspirate liquid from one location to another automatically in accordance with user programmed instructions. The work station is capable of measuring physical characteristics of selected samples and performing experimental assays in a closed loop manner in accordance with those measurements. Fluid is dispensed and aspirated using an interchangeable modules having one or a selected plurality of nozzles. Affixed to the modules nozzles are disposable pipettor tips, which are automatically picked up by the pod and ejected by a tip ejector mechanism at the control of the user. Additional modules may be used to perform Measurement Functions. The work station is designed for interactive connection with a remote computer.
