Cool stamp arrangement for adjusting temperature profile in process area for reaction chamber of assay-processor-cartridge for biological sample analysis, comprises cool stamp, isolated metal body and Peltier element arranged on the stamp

摘要

The cool stamp arrangement for adjusting temperature profile in a process area for reaction chamber of an assay-processor-cartridge for the analysis of biological samples, comprises a cool stamp, an isolated metal body that is movably arranged linear to the surface of the process area to be cooled, a cool stamp area for the reception of a linear drive for viewing a controllable forward and backward movement, and a Peltier element arranged on the cool stamp with cool body and ventilator. The cool stamp is movable by a center hole and cool area for mounting the Peltier element. The cool stamp arrangement for adjusting temperature profile in a process area for reaction chamber of an assay-processor-cartridge for the analysis of biological samples, comprises a cool stamp, an isolated metal body that is movably arranged linear to the surface of the process area to be cooled, a cool stamp area for the reception of a linear drive for viewing a controllable forward and backward movement, and a Peltier element arranged on the cool stamp with cool body and ventilator. The cool stamp is movable by a center hole and cool area for mounting the Peltier element. A nib shaped secondary valve is movably arranged in the center hole for the cool stamp and is held by a screw. An adapter is connected with the linear drive in such a way that a controllable pressure is exercised over a suitable spring against the cool stamp. A multiphase motor or servo gear motor with spindle- or worm gear, a linear multiphase motor, piezo-linear motor, motor with sprocket and gear rack, solenoid, moving magnet, voice-coil-magnet or motor with cam disk are used as the linear drive. The cooling area of the cool stamp is surrounded with a suitable isolation material. A sensor unit and a heat-conducting element are arranged between the cool stamp and the Peltier element for adjusting temperature. The sensor unit is connected by a heat conductive connection or is clenched or screwed with a suitable connection mechanism. An independent claim is included for procedure for adjusting temperature profile in a process area for reaction chamber of an assay-processor-cartridge.
