ABSTRACT:
A cryostatic device employed mainly in infrared spectrometry comprises a vertical open-topped vessel having heat-insulating reflecting walls and containing a cryogenic liquid, an outer enclosure surrounding the vessel and provided with at least one opening for establishing a communication between the external atmosphere and a region of the enclosure opposite to the lower portion of the vessel, means for introducing cryogenic liquid into the vessel and means whereby the sample to be studied is maintained in position and cooled by said cryogenic liquid.
