  • Publication number: 20240050957
    Abstract: The invention concerns a system for controlling the temperature of a microfluidic chip comprising a Peltier module (10) having a cold face (10a) and a hot face (10b) and connected to a power generator (11), a thermal regulation device (12) having a thermal regulated face (12a) applied against one of the faces of the Peltier module, at least one temperature sensor (17) being applied on the other face of the Peltier module and being intended to be applied against one of the main faces of a microfluidic chip and control means (18) configured to control the power generator (11) of the Peltier module depending on a temperature of the face of the Peltier module provided with said at least one temperature sensor and at least one temperature setting information selected from a target temperature and a target temporal temperature profile to regulate a temperature of the face of the Peltier module to said temperature setting information.

  • Publication number: 20160367989
    Abstract: A process for handling an element consisting of a first fluid transported by a second fluid that is immiscible with the first fluid in a cavity having at least one wall of which is made of a deformable material. The second fluid and the element of the first fluid are introduced into the cavity. A local deformation of the deformable material of the cavity is ordered and at least one other portion of the deformable material of the cavity not being deformed. A portion of the deformable material forming the cavity is locally deformed to at least partially obstruct the passage of the element introduced into the cavity without obstructing the passage of the second fluid. The element in the cavity is moved to the outside of the deformed portion of the cavity.

  • Publication number: 20160082365
    Abstract: A device for configuring a multiphase fluid consisting of at least two immiscible phases on either side of separation surfaces. A chamber to contain a multiphase fluid. A temperature gradient generator to generate a temperature gradient along the chamber to vary the surface tension of the separation surfaces along the chamber and to cause at least one of the phases of the multiphase fluid to move. An extractor to extract the multiphase system. Preferably, the temperature gradient generator includes at least one electrical resistor formed on the surface of the chamber to provide a variable heat density along the wall of the chamber.

  • Publication number: 20090163868
    Abstract: Fluid dispensing system comprising a system of interconnected micro chambers (13) communicating with at least a fluid inlet (22) and with at least a suction port (26). Each micro chamber (13) has an output communicating with a needle (15) and has at least one side defined by a deformable membrane (34) subjected to a variable pressure so that a decrease of the pressure with respect to the pressure present at fluid inlet (22) is transferred to the system of micro chambers (13) through the suction port (26) thereby establishing a suction of fluid from the inlet (22) towards the chambers (13) that are filled. An increase of the pressure, causing the deflection of the membrane (34) towards the inner side of each micro chamber, will close each dispensing unit and provoke the ejection of the fluid contained in each chamber (13) of the dispensing unit content through the outlets.
