Abstract
A magnetic type agitator, is provided which has a magnetic agitator element disposed in a magnetically permeable vessel, and a magnetic rotating plate rotatably coupled to the bottom of the vessel. The magnetic type agitator is improved according to present invention in that it further includes a thin ultrasonic vibrating element fixed to the bottom of the vessel, the magnetic rotating plate being placed so as to permit the magnetic force from the magnetic rotating plate to effect the magnetic agitator element, thereby permitting simultaneous agitation and ultrasonic vibration of the liquid in the vessel.
