FIG. 4.

Continuous generation of aqueous droplets in the stream of dichloromethane (DCM) in a T-junction of the FEP device. (a) Schematic illustration of the arrangement of the device. A block of fluoropolymer rubber with cylindrical apertures was used to ensure the connection of the tubes with the inlets and the outlets. (b) A representative optical micrograph showing the formation of aqueous droplets in DCM. (c) A plot showing the lengths of droplets (characterized as their non-dimensional lengths, divided by the width of the channel) over 30 min.
