A cryostat is described for temperature control from 300° to − 150°C. Novel features of this apparatus include a combined heating-cooling thermal exchange coil, good temperature homogeneity over the experimental volume combined with simplicity in design and ease of demountability and maintenance. By using other bath liquids the range of the cryostat can be extended to higher and lower temperatures.
