Description
Spectrum Tube, Deuterium. When viewed through a spectroscope, spectrum tubes reveal the characteristic spectral lines of elements. Like a fingerprint, these lines identify elements and enable astronomers to study the comparison of stars, galaxies, and even the universe.
As one of 2 stable isotopes of hydrogen, deuterium’s spectral lines can be studied for comparison and for additional analysis. The line spectra are quite close, enabling students to precisely measure and compare the spectral lines (or the Balmer line transitions: alpha, beta, gamma, and delta).
The tube design concentrates the gases in the center for better brilliance. Tube is 25 cm L with termination caps at each end. Requires Spectrum Tube Power Supply (item #755400, not supplied).
