ABSTRACT:
A cryostat for subjecting samples to extremely cold or extremely hot temperatures while simultaneously exposing them to a gas. The cryostat includes a temperature control assembly with a cryogen jacket-encased sample tube that defines a sample chamber. A heat exchanger is located at the base of the sample tube. The temperature control assembly further includes an exchange gas system for introducing gas into the base of the sample chamber. The cryostat includes a vacuum tail the temperature control assembly is inserted into. The vacuum tail comprises a vacuum jacket that surrounds the cryogen jacket and the sample base end that is integral with a manifold that is in communication with the sample chamber. Gas introduced into the sample chamber may be exhausted therefrom through the manifold.
