nitrogen can be dispersed, the cells are stored at a low temperature without electric control, meanwhile, according to the different sizes of the gravity of the test tube rack (13), the opening degree of the liquid nitrogen box plate (17) is also different, automatic control can be realized, after the test tube rack (13) descends to open the liquid nitrogen box plate (17), if the gravity of the test tube rack (13) is larger, the downward movement can be continued, at this moment, the switch (15) can be touched, the air pump (20) can be directly opened, part of fog scattered in the liquid nitrogen box (18) can be pumped out through the air inlet (10), the circulating cooling in the device is realized without control, and the automatic control can be realized, and meanwhile, the temperature in the device is synchronously acted on the upper part and the lower part of the test tube rack (13) at the same time, and the uniformity of the temperature in the device is improved.
