| abstract |
An automatic system for analyzing specimens which have been selectively treated. The specimens are arranged in a plurality of specimen trays with each tray containing a plurality of specimens. Tray towers support a plurality of specimen trays. A work station selectively moves the trays one at a time from the tower to selectively deliver reagent or analyze the specimen in the tray. A control system is adapted to sequentially actuate the work station to properly sequence the system so that the reagents are administered to the respective specimen and the specimen have been analyzed after a desired incubating period. |
