Abstract
Multiple piezoelectric elementsare arranged in a row along the top of liquid level in the reaction vessel. An ultrasonic reflecting materialis installed on the bottom of the portion of the heat insulating bathwhere heat insulating mediumis stored. A lateral ultrasonic waveis generated on the lower side is generated by actuation of the piezoelectric element. Waveis reflected by the ultrasonic reflecting material. As a lower ultrasonic waveadvances along the wall surface of the reaction vessel, it collides with the specimen liquid level, thereby causing a portion of the liquid level closer to the piezoelectric elementto be raised. When the lateral ultrasonic waveis applied to this portion, it reaches the inclined portion of the raised liquid level of the specimen. Swirling flow by agitationis produced by the acoustic radiation pressure of the ultrasonic wave. The specimen and reagent are mixed and agitated by this swirling flow.
