Iranian Knowledge-Based Companies Produces Liquid Nitrogen Storage Tanks

According to a report by the news service of the Iranian Vice presidency for Science and Technology, liquid nitrogen tanks are used for storing biological products such as stem cells, gametes, embryos, human and animal tissues and donated organs for transplantation for a long time at a temperature of minus 196 degrees Celsius and with different capacities in the pharmaceutical, health, food, medical and laboratory industries.

One of the knowledge-based companies, after two years of conducting research in cooperation with another knowledge-based company in the field of cryogenic tanks, succeeded in manufacturing two liquid nitrogen storage tanks with a capacity of 1,800 liters for the storage of biological products such as cord blood, bone marrow, peripheral blood, Umbilical cord tissue, fatty tissue and dental pulp.

The structure of a liquid nitrogen tank is a double-walled container in which two tanks are fused together. They are vacuum-jacketed tanks and there is no temperature exchange with the outside environment. For that, the nitrogen temperature inside the tank remains the same and it is possible to save up various samples in it for a long time.

The vacuum aids in the insulation of the inner tank and ensures that nitrogen evaporates much more slowly than it would if simply exposed to air. As long as there is actively evaporating liquid nitrogen still in the tank, the nitrogen vapors inside the tank are as cold as the -320 degrees F liquid nitrogen, keeping semen stored in the tank at an appropriate cryogenic temperature.

Manufacturing these liquid nitrogen storage tanks inside the country put Iran in the list of countries that have the capability to industrially manufacture cryogenic tanks. They can also meet the domestic needs at different centers like labs and medical centers. Moreover, the local manufacturing of these tanks also saves the country huge amounts of money by preventing imports.
