Brief Description: Glass phial, nickel container and small wooden case. The sample is marked 99.75%, which is nuclear reactor grade purity.

Deuterium (an isotope of hydrogen) was discovered in 1931, and heavy water (deuterium oxide), a form of water containing more of this hydrogen isotope than normal water, was first made in 1932. The Norwegian chemical company Norsk Hydro was the first to manufacture it commercially, in 1934, and the only European source during the Second World War, when the plant fell under German control. From 1938 heavy water was used in atomic research and became (and remains) a component of some nuclear reactors, including those intended for making weapons. It also has biological and medical uses, but is neither toxic nor (as often mistakenly thought because of its association with nuclear reactors) radioactive. For further details see narratives.

Another sample is 13525.
