Patent number: 11338289Abstract: 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.Type: GrantFiled: March 29, 2018Date of Patent: May 24, 2022Assignee: FLUIGENTInventors: Clémence Vergne, Benjamin Rouffet, Lionel Matthys, Robert Breton, Nicolas Petit

Publication number: 20140099722Abstract: A method for controlling a flow-rate of fluid flowing in a microfluidic network comprising a microchannel and a plurality of inlet/outlet interface ports is disclosed. The method includes: successively applying a plurality of pressures on at least one inlet/outlet interface port, measuring a time series of flow-rate values of the fluid generated in response to the plurality of applied pressures, estimating parameters of a model of the microfluidic network response to input pressure values based on the applied pressure values and the measured time series of output flow-rate values, computing a target pressure value at each of the inlet/outlet interface ports corresponding to a predetermined flow-rate value at the flow-rate measuring point, wherein the predetermined flow-rate value corresponds to an output value of the model of the microfluidic network response to the target pressure value, and applying the computed target pressure value on the at least one inlet/outlet interface port.Type: ApplicationFiled: October 10, 2013Publication date: April 10, 2014Applicant: FLUIGENTInventors: Thomas Boudot, Nicolas Petit, Stéphane Ritty, Charles-André Kieffer
