Abstract

Thermostatization device for samples for monochromators, of the type that incorporate a chassis in which means are established for the implantation of a glass cuvette, carrier of the sample in question, cuvette that in a situation of assembly, and more specifically the sample established in it, it is located in correspondence with the optical axis of the apparatus, essentially characterized in that said device incorporates, as a thermostatization element proper, a peltier battery, it being provided that the receiving and fixing means for the glass tray, materialize in a base, fixed to the base of the chassis, hollow and container in its core of a thermostatic sensor, preferably a ntc-type probe, from whose base a partition emerges laterally provided with guiding functions for the glass cuvette, whose terna face adapts the peltier battery and from whose outer face they also emerge, laterally, cylindrical bushes spacers through which the fixing of the assembly to the chassis of the monochromator is complemented, specifically to the corresponding side wall thereof, and with the collaboration of screws which, through said bushes, are fixed in threaded holes of said side wall of the chassis, with the particularity that the space defined between the peltier battery and the corresponding side wall of the chassis is occupied by a prismatic, metallic block, preferably made of aluminum, and that the groove is joined to the lower base, in opposition to said partition,, that collaborates in the reception of the glass cuvette and that tends to press the latter against the opposite partition, determining an intimate contact between these elements, while the lateral prismatic block relates the peltier battery to the general structure and of the chassis, determining a large mass of heat dissipation.
