ABSTRACT OF THE DISCLOSURE The present invention provides a cryostat comprising a thermally insulated vessel for storing cryogenic products including a neck, said neck being made of a material with a heat conductivity no. exceeding 0.35-0.4 W/m degree and a tensile strength of 10-20 kg;mm2; a non-metallic stopper having a solid cross-sectional area made of a material having a heat conductivity not exceeding 0.03-0.05 W/m degree and a tensile strength of 5-15 kg/mm2, said stopper being tightly fitted into said neck of said thermally insulated vessel; a helical channel being formed between said stopper and the inner surface of said neck, said channel beginning at one end of said stopper and terminating at the other end thereof for removing vapor of the evaporating cryogenic products into the ambient atmosphere, the ratio of the length of said channel to the cross-sectional area being such that excessive vapor pressure of the evaporating cryogenic products in said vessel is eliminated, while the temperature of said vapor at the outlet of said neck corresponds to the temperature of the ambient atmosphere.
