Abstract
An in-vitro diagnostic analyzer includes an optical detection unit comprising a cuvette for optical measurement of a biological sample, a piezo actuator arranged on one side of the cuvette configured to transmit ultrasonic waves through the cuvette, a piezo receiver arranged on the opposite side of the cuvette configured to receive ultrasonic waves transmitted through the cuvette, and a controller that operates according to a lysis operating mode and/or an air-detection operating mode. In the lysis operating mode, the piezo actuator transmits ultrasonic waves through the cuvette for disrupting cellular particles contained in the biological sample. In the air-detection operating mode, the piezo actuator transmits ultrasonic waves through the cuvette and the controller correlates changes in amplitude and/or shifts of phase of the ultrasonic waves received by the piezo receiver relative to reference values with an eventual presence and quantity of air in the cuvette.
