    Abstract: Die Erfindung betrifft eine Vorrichtung (1a, 1 b) zum Temperieren einer Messzelle (30), insbesondere einer Gassorptions-Messzelle, mit einem isolierten Gefäß (4) zur Aufnahme eines Kühlmediums und einer Messapparatur. Die Messapparatur weist ein Temperierelement (8) mit einer Aufnahmeöffnung (9) zur Aufnahme der Messzelle (30) und eine Kühlvorrichtung zum Temperieren des Temperierelements (8) auf, welche in Richtung einer Längsachse (L) ausgerichtet und wärmeübertragend aneinander anliegen. Die Kühlvorrichtung ist mit einem Befestigungselement (15a, 15b) zum Fixieren des Temperierelements (8) an einer Wandung des Gefäßes (4) und zur Wärmeübertragung zwischen der Messapparatur und dem Kühlmedium ausgebildet. Zwischen dem Temperierelement (8) und der Kühlvorrichtung ist in Richtung der Längsachse (L) ein thermoelektrisches Kühlelement (13) zum Kühlen des Temperierelements (8) und der Messzelle (30) angeordnet. Die Erfindung betrifft zudem ein Verfahren zum Betreiben der Vorrichtung (1a, 1 b) zum Temperieren der Messzelle (30).

    Abstract: : The invention relates to a system comprising at least one disposable comprising one or more wells in a body, wherein the wells are capable of acting as vessel for one or more chemical, biochemical or molecular biological reactions requiring one or more prescribed reaction temperatures according to a prescribed protocol, said body comprising a flat bottom side building a first heating surface capable of homogeneously conducting heat into the wells and a flat upper side comprising well openings sealed by means of a transparent sealing foil building a second heating surface capable of homogeneously conducting heat in the wells, said body being arranged in a rigid frame support; one or more separate tempering units TUx, each tempering unit TUx comprising at least one first temperature-controlled plates with a planar seat to conform to the flat bottom side of the disposable; transport means comprising a carrier in which the disposable is placed and a moving mechanism for moving the disposable into and/or out of the tempering unit TUx and for contacting one of the heating surfaces of the disposable with the first temperature-controlled plates; a control unit comprising one or more processors configured to activate the tempering units TUx and the transport means for the one or more chemical, biochemical, or molecular biological reactions. The solution of the present invention is particularly adapted for high throughput reactions or assay.

    Abstract: The invention is notably directed to a point-of-care diagnostic device (1). The latter includes a fluid-mixing compartment (10) with a conduit (15), a fluid-tight piston (20), and two chambers (11, 13). The piston is slidably movable in the conduit. The chambers comprise a first chamber (11) and a second chamber (13), each communicating with the conduit via a first valve (115) and a second valve (135), respectively. Each of the first valve and the second valve is configured to be actuated by the piston, in operation. The device further includes a reaction chamber (30), which is in fluidic communication with the conduit. The device is configured to controllably move the piston in the conduit, so as to successively actuate the first valve and the second valve, and then adjust the pressure in the reaction chamber for performing a reaction therein. Actuating the first valve allows a liquid sample that initially is in the first chamber to enter the conduit. Actuating the second valve allows contents thereof to admix with the liquid sample, such that an admixture can eventually be obtained in the reaction chamber, which is pressure-adjusted (by controllably moving the piston in the conduit) for performing said reaction. The invention is further directed to related methods of operation.
