Automatic analyzer

An automatic analyzer comprising;

• an analyzer unit to analyze the components of a specimen to be analyzed,
• a heat insulating bath to support a reaction vessel and to hold the heat insulating medium to keep a constant temperature of liquid mixture between said specimen for analysis stored in said reaction vessel and reagent or others,
• wherein the bottom is inclined with respect to said liquid mixture level to serve as an ultrasonic wave reflecting means,
• a controller to administer and control the entire system including said analyzer unit,
• an agitator installed on the side of the reaction vessel supported by said heat insulating bath, wherein
• said agitator comprises multiple ultrasonic generators to generate lateral ultrasonic wave, and
• said agitator mixes and agitates the specimen in the reaction vessel, reagent or the like;
• wherein a position and angle of the bottom is provided so that a liquid level of the liquid mixture being closer to the lateral ultrasonic generator than a center of the liquid mixture is raised higher by a function of a lower ultrasonic wave reflected from the bottom of said reaction vessel toward the liquid mixture level and said lateral ultrasonic wave, and
• an ultrasonic generator drive circuit to supply drive power to said ultrasonic generator.
