ABSTRACT:
The invention relates to a microfluidic device for injecting series of mobile reaction chambers (102, 103) having non-miscible segmenters (101) in micro-channels (21to26), comprising:injection means (10) for injecting into microreaction channels alternatingly and in parallel liquid to form mobile reaction chambers and liquid for forming the segmenters;means for controlling the progression of one of the two liquids, applied to act on one zone (31) of each microchannel delimiting an injection volume of said liquid; the control means being able to cause stopping or slowing of the progression of said liquid over the zone of each microchannel by exerting an action based on a physico-chemical property of the liquid and said action not affecting the other liquid.
