FIELD: packaging industry.SUBSTANCE: device for storing biological material comprises an inner, low-temperature, and an outer, high-temperature chambers, a rack design, a control panel, a compression-condensation unit, a remote compression-condensation device. The inner and outer chambers are isolated from each other and are located one inside the other, and the inner chamber with the walls made of insulating material, with thickness of the at least 120 cm, with refrigeration at least -40°C, with its separate two-stage chilling machine is equipped with several doors. The outer chamber has walls of insulating material with thickness of the at least 80 mm, with refrigeration from 0°C to +5°C, high temperature chilling machine. Using the present invention prevents destruction of the packaging material and freezing it to the grids and provides rational using the volume of low-temperature chamber.EFFECT: reduction of negative impact on the health of the working personnel, prevention of destruction of the packaging material and freezing it to the metal grid, and more rational using the volume of low-temperature chamber.1 dwg |
