ABSTRACT:
A device for the emulsification and separation of small amounts of immiscible liquid phases has essentially a cover plate (2), which can be tightly connected to a base plate (1), where microchannels (4,4a,5,6,6a) in the form of grooves are cut out on the inner surface (3,3a) of the base plate (1) and/or cover plate (2). In a mixing zone, two microchannels (4,4a) run in a wave shape crossing one another a number of times. In a subsequent separation zone, they run essentially straight combined in a common microchannel (5). The otherwise tightly sealed-off microchannels (4,4a,5,6,6a) can be filled and emptied again via inlet apertures (8,8a) and outlet apertures (9,9a).
