<p>Apparatus for carrying out a process between first and second immiscible fluids, comprises first and second channels (2, 4) defining flow paths (24), for permitting fluid flow of respective first and second immiscible fluids therethrough. Portions of the flow paths are disposed close to, or adjacent to, one another and communicate with one another to define a region (3) in which, in use, a stable interface (6) between the fluids is formed. One or more dimensions of the region (3) are varied along the length of the interface (6) in a direction of fluid flow to compensate for variation in the properties of the fluids during the carrying out of the process and thereby maintain stability of the interface (6).</p> |
