Abstract:
A micromixer for chemical reactions of liquid, viscous or gaseous phases comprising: at least two metal housing parts (1 and 2) which bear directly against one another over an interface defined by a parting plane (3) and of which at least a first housing part (1) has line connections which open into the parting plane and a second housing part (2) relieved to define a passage groove (5) opening through the parting plane (3) in communication with the line connections, wherein the line connections are metal supply and discharge capillary tubes (7); wherein in each case one end of each capillary tube (7) is fitted tightly into a transverse hole (6) through the first housing part (1) leading to the parting plane (3) and is secured therein by welding or soldering, and wherein each capillary tube is provided with a screw connection (8) at a free end thereof, whereby fluids introduced into the passage groove from the supply capillary tubes are mixed in the passage groove and removed from the passage groove by the discharge capillary tube.
