ABSTRACT:
A system for performing a plurality of independent analysis procedures simultaneously, each procedure having a sample and at least one process step for operating on that sample the system having a robotic device for moving a sample among a plurality of processing stations where the robotic device comprises substrate to which are coupled a plurality of tiles each one of the tiles disposed at a selected location on the substrate; a plurality of reagent trays coupled to the tiles, each one of the reagent trays having substantially identical shape and size; a robotic arm disposed for reaching substantially all the tiles; and capable of coupling and decoupling from a sample holder, the sample holder capable of holding at least one sample in a selected position, whereby the robotic arm is capable of moving the sample from a first one of the reagent trays to a second one of the reagent trays; and a processor for selecting, at a plurality of times a sample to be moved, and for directing the robotic arm to move the sample to be moved; the processor capable of directing the robotic arm to interleave the process steps of the plurality of independent analysis procedures in a sequence conforming to a predetermined range of durations for each one of the process steps.
