ABSTRACT:
A heating and temperature-control device for biological sample containers includes an assembly of lamps emitting infrared radiation within a wavelength of 1-5.5 micrometers and heating said containers by irradiation, and a sensor for infrared radiation of wavelength 7-14 micrometers which picks up the emission from the containers which derives from their heating. The signal obtained from said sensor is used to control the lamp emission in such a manner as to obtain the required container temperature and then keep it constant.
