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.
Claims20
An ultrasonic horn assembly comprising:
- an ultrasonic horn or probe having an axis and a distal end with an end face oriented substantially transversely to said axis, said end face being disposed at least approximately at an antinode of ultrasonic vibration of said horn or probe;
- and
- a cup member attached to said horn or probe at least approximately at said antinode so as to define a liquid reservoir covering said end face of said horn or probe.
An ultrasonic horn assembly comprising:
- an ultrasonic horn or probe having an axis and a distal end with an end face;
- a cup member attached to said horn or probe at least approximately at said antinode so as to define a liquid reservoir covering at least said end face of said horn or probe, said cup member having a sidewall and a lower wall or flange extending inwardly from said sidewall;
- and
- at least one port provided in said lower wall or flange for feeding liquid to said reservoir.
