Abstract
An automatic continuous multinominal analyzer comprises suction tubes to be inserted into vessels containing a reagent, each suction tube having a pair of electrode lines. The contacts of each pair of electrode lines are located above the suction port of the suction tube. Hence, the contacts are isolated from each other when the level of the reagent in a vessel is lower than the contacts, even if the reagent still remains in the vessel. If it is detected that the contacts in a vessel are isolated, this indicates that the vessel is almost empty. A display indicates a vessel which is almost empty on the basis of the result of the detection as to whether the contacts in the vessel are isolated. After a vessel is indicated on the display, the controller continues suction of the reagent and an analysis operation until the reagent in the indicated vessel is reduced to the minimum level which can be extracted through the suction tube. After the display indicates a vessel, the operator prepares to exchange the vessel with a new one filled with the reagent before the reagent in the vessel is reduced to the minimum level.
