Helium Gas UHP 99.999% for MRI & Welding
Helium is a colorless, odorless, tasteless and gaseous atmospheric gas. It has the lowest critical temperature at normal temperature. It is the most difficult gas to liquefy in nature. Ammonia has extremely low chemical reactivity and cannot be burned or combustible. The amount of helium in the air is approximately 5.2 parts per million. It can theoretically be extracted from the air, but its content is extremely low and the separation cost is high. Liquid helium, due to its low boiling point of -268.9°C, can be used for ultra-low temperature cooling.
