Abstract: The invention concerns a system for energy and environmental optimisation of a facility comprising at least one combustion apparatus (1) with a burner (3). The system comprises an electrolyser (2) and an injection system (4) connected to at least one fuel (3a) and/or oxidant (3b) inlet of the burner (3). The injection system is capable of injecting, at such an inlet, gases from the electrolyser (2) and/or a mixture of these gases and a combustible fluid and/or an oxidising fluid. The electrolyser (2) and/or the injection system (2) are controlled on the basis of at least one piece of information originating from the combustion apparatus (1) and/or sensors (6x) of the installation. The electrolyser can comprise a heat exchanger (2a) for cooling the device and/or preheating the water (EP) that is intended to then be heated (EC) by the combustion apparatus (1).

Abstract: The invention relates to a system for treating hydrogen and/or oxygen gas produced by water electrolysis and serving to supply a combustion process, characterised in that it comprises at least one heat exchanger, in which the one or more gases circulate so as to be cooled or heated, said heat exchanger being submerged in a reactive compound through which the one or more gasses pass in turn.

Abstract: A fluid connection device is provided for biological analysis apparatuses, intended to simultaneously connect a plurality of fluid conduits and at least one fluidic component including a connecting surface with a plurality of fluid ports, the device having: (i) a holding plate, (ii) removable attachment structure capable of pressing the holding plate against the connecting surface, (iii) connectors suitable for being fixed to the ends of the fluid conduits and provided with a seal suitable for allowing a sealed connection to be made between the connectors and the fluid ports, holding plate including through-openings opposite the fluid ports and being shaped in such a way as to be able to receive the connectors in through-openings and to hold them pressed against the connecting surface. A biological analysis apparatus implementing the device is also provided.

Abstract: A method and a device employing the method of flow cytometry, preferably applicable but not limited to the counting and differentiation of leukocytes. It relates more particularly to the field of simplified haematology instruments with moderate operating costs. The method is characterized in that a technique of impedance measurement is used for identifying the particles whose trajectory did not pass through a predetermined optical measurement zone in order to process them selectively, thus avoiding the use of sheath fluids for guiding the particles towards the measurement zone.

Abstract: A syringe block (1) includes a plurality of syringes (2) and a collector (3), the syringes each having a suction volume, and the collector includes electromagnetic valves. First tubes directly link the electromagnetic valves to the internal volumes and second tubes extend from the electromagnetic valves towards the containers for the sample and/or other liquids, at least one of the syringes being an air pump (15, 16). The syringe block can be used as a support for various components used for the operation thereof, and can be arranged in a climatic condition reproducer. One such syringe block is especially adapted to be used in a liquid analyser, the air pump being used especially to take a sample and/or to drain and clean different recipients containing a sample.
