Patent ID: 7910073

Claim:
A microfluidic system, comprising: a plurality of modules arranged in series next to each other, wherein each module has a microfluidic unit and an associated electric control unit, and wherein each module has an electric connector on a rear face of the module; a common vertical rear wall unit, wherein the rear faces of the modules lie against the common vertical rear wall unit and are held against the common vertical rear wall unit; an electric line bus extending through the rear wall unit, wherein the rear wall unit has electric connectors, wherein the control units are connectable to the electric line bus extending through the rear wall unit via the electric connectors arranged on the rear faces of the modules and on the rear wall unit; a connecting part with connection channels to span two adjacent modules, wherein the microfluidic units of the two adjacent modules are interconnected via the connection channels to allow a passage of fluid; a fluid conduit for a rinsing fluid extending through the rear wall unit; branches leading from the fluid conduit to the modules, wherein the branches each flow into a distributor compartment which extends vertically across the module height in the modules, wherein the distributor compartment is delimited in relation to an interior of the respective module by a distributor panel having openings, wherein the rinsing fluid is equally distributed over the distributor compartment and the openings in the distributor panel across the module height into the interior of the module; and an exit opening for the rinsing fluid on the lower or rear surface of the module; wherein the control unit is arranged in the module in a compartment, wherein the compartment is shut off in relation to an area rinsed by the rinsing fluid; wherein the compartment containing the control unit is on the rear face of the module, and wherein the control unit is thermally connected to the rear wall unit and blower-cooled by the rear wall unit using a ventilator blowing on a cooling fluid or conveyed past a Peltier element in the rear wall unit.
