Hydrogen Gas Spectrum Tube Apparatus Versatile Connector: The Retractable StackingIncluded: Hydrogen Gas Spectrum Tube Apparatus with Protective Case. Used to light a characteristic color for Hydrogen gas. Sealed metal electrodes are located at the ends of each tube. When a spectrum tube is placed in a spectrum tube power supply and the power supply is turned on, an electrical discharge is passed through the tube, causing electrons in the gas to be excited. As the electrons relax, they emit light a characteristic color for each
