摘要： A method of producing variable temperatures with the aid of a cryoliquid, wherein the cryoliquid is throttled in a heatinsulated section at a point having poor heat conductivity, and at a distance from this point there is produced a variable temperature adjustable to values greater or equal to the boiling temperature of the cryoliquid, and apparatus for carrying out the method comprising a supply vessel for low-temperature gas, an evaporating device in which the low-temperature gas is arranged to be evaporated and at which the refrigerating output is arranged to be collected, and a regulating device for adjusting a predetermined temperature at the evaporating device, wherein the supply vessel is connected to a heat-insulated section, a heatinsulating flow resistor is arranged in the heat-insulated section, the heat-insulated section is sealed off by a gas-tight closure by which an evaporation chamber is defined, and a heating device with variable heating output is arranged at a distance from the flow resistor.
