<p>An ultrasonic horn assembly (10), particularly suitable for dissolving reagent tablets in a liquid solution in a cuvette (20) which is moved along a path next to the front end face (22) of the horn (10), includes a generally cylindrical converter (14) fixed to a rear end face (24) of the horn body (12) substantially medial of the length of the rear end face (24). A pair of elongate resonating members (16a, 16b) are each fixed at one end to a different side end region of the rear end face (24) on the horn body (12), and extend perpendicularly from the rear end face (24). The resonating members (16a, 16b) cause acoustic waves to propagate from the front end face (22) of the horn body (12) at substantially uniform amplitude along the length of the front end face (22), so that objects such as cuvettes (20) moving parallel to the front end face (22) are continuously subjected to uniform acoustic waves to insure a thorough dissolving or mixing operation.</p> |
