Characterisation of asynchronous oil droplets at various combinations of oil and water pressure: (a) Droplet generation map, showing the existence of ‘dripping’, ‘chained dripping’, ‘threading’ and ‘unstable’ modes. Average ± standard deviation values are based on 10–50 droplets per each experiment according to the stability of droplets, with 4 experimental repeats for each device, and 3 devices being used for each experiment. (b) ‘Dripping’ mode corresponding to the asynchronous generation of droplets at the orifice. (c) ‘Chained dripping’ mode corresponding to generation of droplets that are separated by a thin layer of water. (d) ‘Threading’ mode corresponding to the advancement of oil columns through the orifice and the asynchronous generation of droplets along the sidewalls. Increase of oil pressure leads to the formation of long droplets that are separated by a thin thread of water. Scale bars are 500 µm.
