In a static micromixer for mixing at least two fluids including a flow guide structure having a longitudinal axis extending in the general flow direction of the fluids through the guide structure, separate fluid admission areas disposed at the entrance end of the flow guide structure and a mixing chamber disposed at the exit end of the flow guide structure, the flow guide structure is formed by foils of a thickness of about 100 .mu.m disposed on top of each other and having parallel grooves extending in one foil from one of the fluid admission areas at an angle with respect to the general fluid flow direction through the flow guide structure to the mixing chamber and in an adjacent foil from another of the fluid admission areas to the mixing chamber such that in the mixing chamber the fluid exits of different foils are disposed adjacent each other, the grooves having a width of less than 250 .mu.m and being spaced from each other by less than 70 .mu.m to provide for the fluid flow filaments entering the mixing chamber at different angles and closely adjacent each other.

Static micromixer with heat exchanger

In a micromembrane pump with pump housing top and bottom parts and a membrane structure disposed between the housing top and bottom parts such that pump chambers, valves, flow channels and a cavity system are formed between the membrane structure and the housing parts, heating means are disposed on the membrane structure in the area of the pump housing for operating said pump and the cavity system is filled with a cement for joining the membrane and the housing parts.

Micromembrane pump

In a micro diaphragm pump which has a pump body consisting of two parts, one part including two valve chambers with a pump chamber disposed therebetween and in communication with the valve chambers by passages, a diaphragm extends across and closes the chambers and forms, in the areas of the valve chambers, valve membranes for inlet and outlet valves which are integrally formed, both on one side of the diaphragm, both pump body parts being sealingly connected to the diaphragm.
