Claim 9:
10. A method for generating bubbles or droplets, the method comprising:
generating bubbles or droplets using a device comprising a cavity comprising a first pressurized phase, at least one input capillary of a second phase, and an output capillary coaxially aligned with the at least one input capillary, 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;
observing the bubbles or droplets using a control unit connected to a means for observing the bubbles or droplets in the output capillary,
determining a diameter of the bubbles or droplets using the control unit; and
regulating the diameter of the bubbles or droplets according to a predetermined value by controlling the pressure of the first and second phase using one or more pressure regulators, wherein the diameter of the bubbles or droplets is at least two times bigger than the output diameter of the tip of the at least one input capillary.
