A microfluidic apparatus for producing an emulsion, comprising at least one fluid inlet channel (4) configured to allow an aqueous solution to flow therealong and at least one fluid inlet channel (2) configured to allow an oil phase to flow therealong. Each inlet channel converges at a junction (8) at which an emulsion is formed upon contact between the oil phase and aqueous solution. The apparatus further comprises a fluid outlet channel (22) extending away from the junction, and configured to allow the emulsion to flow therealong. Each inlet channel comprises a restricted section (10, 16) disposed at least adjacent to the junction, and an expanded section (14, 20) disposed upstream of the restricted section, wherein the expanded section has an aspect ratio which is greater than 20:1. |
