Product descriptions from the supplier
Helium is a colorless, odorless, and gaseous atmospheric gas at normal temperature with the lowest critical temperature. It is the most difficult gas to liquefy found in nature. Helium gas has very low chemical activity and cannot be burned or combustible. Helium in the air is about 5.2 parts per million and can theoretically be extracted from the air, but it is so thin that it is expensive to separate. Liquid helium can be used for ultra-low temperature cooling with its low boiling point of -268.9 ℃.
