A cryostat includes a case 1 having a lid 3, and coaxially disposed liquid 5 and solid 9 nitrogen vessels placed therein. The case has decomposable construction, and is made with mirror-polished stainless steel, wherein the vessels are hermetically hung on the lid by means of liquid nitrogen pouring and evaporating gas release tubes 6; and siphon thermodemper to reduce heat flows. At that, cylindric high-temperature superconductors (HTS) research cup-chamber 10, wherein a solenoid is placed, is built-in into solid nitrogen vessel, the HTS physical parameters measuring sensors 15 and special purpose rope, whereon the superconducting sample is fastened, and cryosorption pumps 8 and 11, having copper optically opaque porous screen, are built-in into the liquid and solid nitrogen vessels from bellow. Furthermore, vacuum valves 20, emergency valve 16, and inert air inlet valves 19 are located on the lid.
