Patent ID: 8062594

Claim:
An automatic clinical analyzer having a fluid handling system for storing and supplying a number of liquid solutions consumed therein, the analyzer comprising: a reaction carousel supporting reaction cuvettes for containing assay mixtures; a plurality of probes for supplying sample and reagent mixtures into the cuvettes; a plurality of assay operational devices that operate on the sample and reagent mixtures in the cuvettes; a plurality of detector units to perform clinical analytical measurements on the sample and reagent mixtures in the cuvettes; a plurality of different containers that contain sample and reagent probe cleaners, a system diluent, or a reaction cuvette wash solution, each container having opposed top and a bottom surfaces, the bottom surface includes a front tapered portion with a mounting fin and an opening depending therefrom, each of the mounting fins having a different pattern of at least one open notch therein, each container further including opposed side surfaces and opposed front and back surfaces, the opposed side surfaces having alignment ridges extending therefrom and positioned between a centerline of the side surfaces and the front surface; and a plurality of container mounting brackets, each bracket having a mating key with a pattern of closed and open sections that match only one of the open notch patterns in the mounting fins so that only one of the different containers can be mounted in each of the container mounting brackets.
