Abstract

Dividing drops at a microfluidic junction comprising a first supply channel, a second supply channel and a discharge channel, comprises (a) supplying the drops (1) to the microfluidic junction (3) through the first supply channel (2) by flowing continuous liquid through the channel and the discharge channel, (b) adjusting the flow in the first supply channel to a time point, at which the drops are present in a lumen of the second supply channel, and (c) opening the flow of the continuous liquid in the second supply channel up to a time point, at which the drops are divided into two portions.
