Glass Cell (IMAGE) ICFO-The Institute of Photonic Sciences Caption Picture of the glass cell that where the rubidium metal is mixed with nitrogen gas and heated up to 450 degrees Kelvin. At that high temperature, the metal vaporizes, creating free rubidium atoms that diffuse around inside the cell.
