Claim 0:
1. A device for generating bubbles or droplets, the device comprising:
a cavity comprising a first pressurized phase;
at least one input capillary of a second phase;
an output capillary coaxially aligned with the at least one input capillary;
means for observing the droplets produced, in use, by the device in the output capillary; and
a control unit coupled to the means for observing the droplets, the control unit being configured to determine a diameter of the droplets and to control the pressure of the first and second phase to regulate the diameter of the droplets according to a predetermined value;
wherein an opening of a tip of the at least one input capillary has an internal diameter of less than half the internal diameter of the output capillary; and
wherein all dimensions of the cavity are larger than 3 mm, and the output capillary has a hydraulic diameter smaller than 500 μm.
