According to the structure, the classification of liquid nitrogen tanks is a storage type and a transportation type;
From the name, one is for storage and the other is for transportation. Combined with the function of the liquid nitrogen container itself, they store and transport liquid nitrogen, or liquid nitrogen + samples. That is to say, the liquid nitrogen transport container can transport liquid nitrogen and transfer samples.
Moreover, judging from the product descriptions of major liquid nitrogen tank manufacturers, the liquid nitrogen transport container is the main transportation, and the long-term static storage effect of using it for liquid nitrogen and samples is not as good as that of storage type liquid nitrogen tanks. Why?
It is also a combination of aviation aluminum + vacuum insulation structure, why can the liquid nitrogen transport container be used to transfer samples?
Because the interior of the liquid nitrogen transport container is supported, the three-side support provides good protection for the inner tank, making it not afraid of bumps and shaking during transportation, and will not affect the upper neck tube, causing the neck tube to fall off and the tank Vacuum disappears. Therefore, it can, but the storage type liquid nitrogen tank without liner support cannot.
In addition, it should be noted that there are also restrictions on the use of transfer samples in liquid nitrogen transport containers. If it is by public transportation, such as airplanes and high-speed rails, it is not allowed. A special dry container is required for boarding the plane, and no liquid in it can pass the security check.
Transfer samples in liquid nitrogen transport tanks are limited to private cars and special vehicles, because they are only stored in liquid phase like storage tanks, and there is liquid in the tank, which is not accepted by public transportation security checks.
