Abstract
Microfluidic device comprising a tank (6) supplying a microchannel (2) with a first fluid (S), and a circuit (8) in which a flow of a second fluid can be established without contact with the microchannel (2). The circuit (8) passes through the tank (6) or is connected to the tank (6) by a pipe (30). The circuit (8) comprises a first on/off valve (12) mounted in parallel with a first proportional valve (11), these first valves (11, 12) being controllable so as to modify the pressure applied in the tank (6) to the first fluid (S) by the second fluid.
Claims20
A microfluidic device comprising a tank supplying a microchannel with a first fluid, and a circuit in which a flow of a second fluid can be established without contact with the microchannel,
- wherein the circuit passes through the tank or is connected to the tank by a pipe, and
- wherein the circuit comprises an on/off valve mounted in parallel with a proportional valve, a maximum opening cross-section of the proportional valve being smaller than a maximum opening cross-section of the on/off valve, the proportional and on/off valves being controllable so as to modify a pressure applied in the tank to the first fluid by the second fluid.
