First of all, we can make different disposal methods according to the specific specifications of the liquid nitrogen tank used. If the liquid nitrogen tank you are using has a relatively large caliber and a relatively large volume, if you use the method of pouring out the liquid nitrogen to take out the specimen , It is more difficult to operate, and the liquid nitrogen tank with a larger volume is not suitable for dumping operations, and the risk is higher. Once this happens, don’t worry too much. If there are many samples spilled, you can use a small colander to pick them up. Wear liquid nitrogen protective clothing when picking them up, and protect your face and hands to avoid frostbite.
