We introduce here a new microfluidic device for the rapid formation of monodisperse double emulsions. The device consists of three coaxial capillaries set in a single block of ultra-high molecular weight polyethylene (UHMWPE). We characterize the water-in-oil drop formation by measuring the diameter of the drops produced as a function of varying inner and outer Reynolds, Weber, and Capillary numbers. These parameters were subsequently used to characterize the dripping to jetting transition across a wide range of capillary channel diameters. We also observe that when produced using solutions of amphiphilic block copolymers, the double emulsions produced can be processed to form large numbers of monodisperse polymersomes in a highly efficient and controlled manner.
