Abstract
An ultrasonic sonication device includes a velocity transformer or probe which, when coupled to a vibrating transducer of the piezoelectric or magnetostrictive type, resonates in sympathy with the transducer and either increases or decreases the magnitude of the transducer's vibration. A shallow cup assembly is attached to the distal end of the probe. The cup assembly holds a microtiter tray in a suitable orientation and contains an amount of liquid which provides efficient acoustic coupling between a transverse end face of the probe and the microtiter tray.
