Cryotank or cryogenic tank is a tank that is used to store frozen biological material.

Cryotanks and cryogenics can be seen in many sci-fi movies but today, it is still an up and rising technology. The term “cryotank” refers to storage of super-cold fuels, such as liquid oxygen and liquid hydrogen. The premise of it seems very simple. All that needs to be done is for a human to be loaded into the tank and then they can be frozen until a time comes when any diseases they have can be cured and they can live an even longer life. This could also be used in space travel and just preserving human life in general. The problem with this is when the human body is frozen, ice crystals form in the cells. The ice crystals then continue to expand rupturing the cell wall and destroying the integrity of the cell, or killing it.
This means in order for humans to undergo the cryogenic process a way to significantly raise the levels of glucose produced in the human body is needed.
In fiction
Cryogenic Tanks are used to store natural gases such as oxygen, argon, nitrogen, helium and other materials. By putting them in these tanks they can be stored at the correct temperature and pressure to be transported to different areas that need them for use.
In science fiction
In science fiction, it is used to freeze people. (cry- is a Greek prefix which means "cold or freezing") So people are stored in the tank frozen to come out in the future. Cryotanks are found in some science fiction films such as Prometheus (2012) and The Host (2013).
