Patent ID: 8534447

Claim:
A microplate handling system, comprising: at least first and second non-priority microplate storage units that each store two or more microplates; at least one priority microplate storage unit that stores at least one microplate; at least one microplate processing area; at least one non-priority microplate holding area; at least one microplate transport mechanism configured to transport one or more microplates between the first and second non-priority microplate storage units, the priority microplate storage unit, the microplate processing area, and/or the non-priority microplate holding area; and, at least one controller operably connected at least to the microplate transport mechanism, which controller is configured to selectively direct the microplate transport mechanism to: (a) transport a non-priority microplate from the first non-priority microplate storage unit to the microplate processing area; (b) position the non-priority microplate while in the microplate processing area; (c) transport the non-priority microplate from the microplate processing area to the non-priority microplate holding area when a priority microplate is stored in the priority microplate storage unit; (d) transport the priority microplate from the priority microplate storage unit to the microplate processing area; (e) position the priority microplate while in the microplate processing area; (f) transport the priority microplate from the microplate processing area to the second non-priority microplate storage unit or to the priority microplate storage unit; (g) transport the non-priority microplate from the non-priority microplate holding area to the microplate processing area; and (h) transport the non-priority microplate from the microplate processing area to the second non-priority microplate storage unit.
