Abstract: Disclosed herein is an automatic analyzer that includes one or more pipetting probes for pipetting reagents or samples to be examined, one or more pipetting-probe-transferring means for transferring the probes and one or more washing tubs installed on the transfer paths of the probes and having structure permitting the probes to pass therethrough. The washing tub has washing-water-discharging orifices for discharging washing water and air-jetting orifices for jetting out air.

Abstract: An object of the present invention is to provide an automatic analyzer which measures blank values for each vessel to reduce analysis time. The automatic analyzer comprises: a vessel for storing a sample and a reagent; a cleaning mechanism for cleaning the vessel and; an analysis mechanism for performing photometric inspection of reaction of the reagent and the sample; wherein the automatic analyzer includes a blank value comparison function for comparing a preceding blank value with a succeeding blank value. The preceding blank value is measured before photometric inspection of the reaction in the initial starting operation initially performed. The succeeding blank value is measured after photometric inspection of the reaction in the running operation subsequently performed after the initial starting operation.

Abstract: In an automatic analyzer, effect is reduced or prevented of a change in temperature and volume of components making up a mechanism for dispensing a reagent and a sample or a system liquid on an amount of sample and reagent per one dispensing cycle. One or a plurality of components making up the mechanism for dispensing the reagent and the sample is mounted with a sensor for measuring a temperature of the component. The dispensing mechanism further includes a sensor for measuring a temperature of the system liquid at one or a plurality of locations. Control is thereby provided, based on temperature information provided by the temperature sensor, to vary an amount of operation of a component that varies an amount of reagent and sample to be dispensed or to make the temperature of the system liquid equal to, or close to, the temperature of the component.

Abstract: The present invention provides an automatic analyzer making it possible to reduce the cost for serum information measurement and prevent a decrease in processing capacity. An automatic analyzer comprises a calorimetric analysis section provided with a reaction vessel to mix a sample with a reagent and a measurement section to measure the color change of the mixture in the reaction vessel; and an electrolyte measurement section to measure the concentrations of electrolytes in a sample, wherein the sample included in the reaction vessel is diluted to be measured in the measurement section of the calorimetric analysis section, and at least one of the degrees of hemolysis, lipemia and icterus in a sample is measured in the electrolyte measurement section.
