Maintenance methods of liquid nitrogen storage tanks 2
Check the neck plug and the small groove of the neck plug at any time.
Check the neck plug and the small groove of the neck plug at any time, remove the ice on the neck plug in time, and do not place plastic cloth and other materials on the neck plug to increase the sealing performance and ensure the performance of the liquid nitrogen storage tank. When it is found that the liquid nitrogen is consumed too quickly or there are water droplets and white frost near the neck of the liquid nitrogen storage tank, it means that the insulation function of the tank is out of order and the liquid nitrogen cannot be retained. The specimens placed in the liquid nitrogen tank should be marked, and they should be taken and placed steadily, accurately and quickly.
