1- It is virgin heavy water and its tritium is not detectable in the range 
of <2 μCi / L
2- Its isotopic enrichment is more than 99.95 atom D%
3- It is packaged in 50 kg keg under Nitrogen gas blanketing
4- None of heavy metals such as Gadolinium were added to our heavy water so 
that it is highly pure and could be safely used in bio deuterium labeling or 
neutron scattering experiments and to be electrolyzed and produce D2 gas 
that is going to be used in electronic and deuterium labeling industry.
