Patent ID: 8163245

Claim:
A microfluidics system for mixing at least two starting materials, comprising: a predetermined number of parallel and identical mixing or reaction branches, each of the mixing or reaction branches having a plurality of supply ducts which correspond to the number of starting materials, said plural supply ducts issuing into a mixing or reaction duct; respective intake lines for each of the starting materials; respective injection pumps for each of the supply ducts; respective valve circuits for each of the intake lines, each valve circuit arranged between a respective intake line, the plural supply ducts associated with the respective intake line, and the injection pumps associated with the respective intake line; wherein said each valve circuit is configured, in a first valve position, to connect each respective injection pump associated with the respective intake line to the respective intake line, configured in a second valve position to shut off the each respective injection pump associated with the respective intake line, and configured in a third valve position to connect the injection pumps associated with the associated intake line to respective ones of the supply ducts associated with the respective intake line; wherein, for each of the valve circuits, each of the injection pumps connected to a respective one of the valve circuits are fluidically connected to one another in the second valve position; and wherein, for each of the valve circuits, each of the injection pumps connected to the respective one of the valve circuits are connected to a common drive.
