A system for managing bulk liquids for an automated clinical analyzer. The system comprises (a) at least one local reservoir for storing a bulk liquid for impending use, (b) at least one container for holding a bulk liquid before the liquid is transferred to a local reservoir, and (c) a controller for monitoring the level of a bulk liquid in a local reservoir. The local reservoir for storing a bulk liquid for impending use can be a trough. The use of troughs for storing a reagent, a diluent, or some other treating agent for impending use enables an aspirating/dispensing device having a plurality of pipettes to aspirate and dispense the reagent, diluent, or other treating agent at a high rate of throughput. The controller can monitor the level of a liquid in (a) a local reservoir for storing a bulk liquid for imminent use and the level of liquid in a (b) container for holding a bulk liquid before the liquid is transferred to a local reservoir. In the laboratory automation system described herein, the container for holding a bulk liquid before the liquid is transferred to a local reservoir can be a bottle. Other desirable features in the system include, but are not limited to, pump(s), valves, liquid level sensors. |
