Both channels will end in a so called flow-focusing cross junction, where the droplets will be formed. The fluids will first pass a filter to minimize blockage at the cross junction nozzle.

It is possible to control the droplet size and droplet formation frequency, by alternating the rates of the oil phase and the water phase.</p> | <p>To answer the questions mentioned at the introduction, a droplet device with a single oil inlet and a single water inlet is used (<nobr><a href='#Fig3'>Figure 3</a></nobr>).
