Abstract: An ultrasonic disintegrating apparatus with a tank containing a liquid, an ultrasonic wave generating device operatively coupled to a bottom wall of the tank, and at least one vessel vertically immersed in the liquid contained in the tank such that ultrasonic waves propagated from the bottom wall of the tank disintegrate cells in the vessels. Each vessel includes a cylindrical metallic tube having an open upper end and a closed lower end, a cap detachably coupled to the open end of the tube, and a downwardly depending metallic bar suspended from the center of the cap into the metallic tube so as to terminate at a point spaced from the lower end of the metallic tube to thereby facilitate complete disintegration of cells within the vessel when exposed to ultrasonic waves.
