Abstract: Apparatus and methods for producing a drop from a Drop on demand (DOD) dispenser, the drop having a radius that is much smaller than the radius of the nozzle that expels the drop. Generally, the Ohnesorge number is less than about 0.1. Various embodiments of the invention are found within a four dimensional space defined in terms of the Ohnesorge number, the Weber number, the actuation frequency, and the initial conditions.
