Before use, a small amount of liquid nitrogen should be placed in the liquid nitrogen tank to pre-cool it. When the temperature inside the tank reaches liquid nitrogen temperature, fill the tank with liquid nitrogen. Handle the liquid nitrogen tank with care to avoid bumping or squeezing. Do not drag it on the ground; lift it up when moving. When not in use, store the liquid nitrogen tank in a dry, well-ventilated room to prevent moisture.
Check the neck plug and the grooves regularly, and remove ice from the neck plug promptly. Do not place plastic sheeting or other materials on the neck plug to enhance sealing and ensure the proper function of the liquid nitrogen tank. Rapid liquid nitrogen consumption or the formation of water droplets or frost near the neck of the liquid nitrogen tank indicate a malfunction in the tank’s insulation and its inability to retain liquid nitrogen. Specimens placed in the liquid nitrogen tank should be clearly marked, and handling should be steady, accurate, and quick.
To prevent corrosion of the tank wall, the interior of the liquid nitrogen tank should be cleaned annually. Additionally, minimize transportation of cryogenic storage tanks and the number of times they are opened. If transport is necessary, secure the tank to the vehicle with ropes to keep it upright. Avoid dropping, tipping over, or lying flat, and minimize severe vibration.
