Spectrum Tubes

(Air, Argon, Carbon Dioxide, Deuterium, Elium,Hydrogen, Nitrogen, Water Vapor, Krypton, Xenon, Mercury, Neon)
Each tube shows its characteristic spectrum when energized before any spectroscope. Tubes require a power source such as tesla coil 15583518 on page 478, any of our induction coils, or power supply above. Includes instructions giving spectral line information.
