Abstract (en)

There is provided a microreactor that has a simple structure and prepares stable monodisperse droplets over a long period of time, with simple modifications to a conventional microreactor. A microreactor 1 that includes flow channels 2 formed by the lamination of a plurality of substrates so as to allow fluids to flow therethrough, and prepares droplets by causing a continuous phase fluid to shear a dispersed phase fluid, has an integrated lamination of: a flow-channel substrate 5 including the flow channels 2 formed open, through which the continuous phase fluid and the dispersed phase fluid flow, and also including a merge section 3b formed open where the flow channels 2 merge; spacer substrates 4 and 6, either or both joined to one side or respective sides of the flow-channel substrate 5 and including space portions 3a and 3c each formed so as to have a predetermined space in a corresponding one of the vertical directions with respect to the merge section 3b of the flow-channel substrate 5; and cover substrates 7 and 8 joined to respective outer sides of the lamination of: the spacer substrates 4 and 6 and the flow-channel substrate 5, the spacer substrates 4 and 6 joined to the respective sides of the flow-channel substrate 5; or the flow-channel substrate 5 and the one of the spacer substrates 4 and 6, the spacer substrate joined to the one side of the flow-channel substrate 5, so as to close both outer sides.
