Abstract: A process module for a biology laboratory system includes a housing, a working deck located within the housing, having working deck plate slots for receiving cell culture plates, a liquid handling robot comprising at least one pipette for aspirating a liquid medium, and a first transfer interface in communication with a first storage module for storing cell culture plates. The working deck is movable to a plurality of working positions. In one of the positions, the cell culture plate is located under an operating point of the liquid handling robot. In another of the positions, the cell culture plate is in alignment with the first transfer interface for transfer of the cell culture plate between an outside of the housing and the working deck plate slot. The first transfer interface or a second interface can be brought in communication with a second storage module for storing lab-ware or liquid material.
