A microfluidic dispensing device has a plurality of chambers arranged in sequence, each having an inlet receiving a liquid to be dispensed and a nozzle for emitting a drop of liquid. An actuator in each chamber receives an actuation quantity and causes a drop of liquid to be emitted by the nozzle of the respective chamber. A drop emission detection element in each chamber generates an actuation command upon detecting the emission of a drop of liquid. A sequential activation electric circuit includes a plurality of sequential activation elements, one for each chamber, each coupled to the drop emission detection element of the respective chamber and to an actuator associated with a subsequent chamber in the sequence of chambers. Each sequential activation element receives the actuation command from the drop emission detection element associated with the respective chamber and activates the actuator associated with the subsequent chamber in the sequence of chambers.
