Abstract
A cuvette whose outer side has a recess for a flat square resistance thermometer which is bonded to a thin partition between the recess and the internal space of the cuvette. The thermometer is connected with a device which indicates the temperature of a sample in the cuvette and/or which regulates the temperature of the sample if such temperature deviates from an optimum value. The contacts of the thermometer are soldered to the corresponding conductors of a cable. The joint between the contacts and the conductors as well as the thermometer and its contacts are confined in the recess by a mass of epoxy resin. The thickness of the partition is a fraction of one millimeter, and the thermometer is bonded to the outer side of the partition by a heat-conducting adhesive.
