Abstract (en)

[origin: WO0146714A1] An ultrasonic sonication device includes a velocity transformer or probe (32) 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 (48) is attached to the distal end (36) of the probe. The cup assembly (48) holds a microtiter tray in a suitable orientation and contains an amount of liquid (58) which provides efficient acoustic coupling between a transverse end face (38) of the probe and the microtiter tray.
