Elecopto Helium Usa Type Spectrum Discharge Tube Glass Demonstrate Spectral Lines Pure Substances

Features a toxic-free helium gas filling
Optimized for adult use alongside standard induction coil

The Elecopto Spectrum Discharge Tube Usa Type Helium is a high-grade laboratory apparatus designed to demonstrate the distinct spectral lines of pure substances. Built using a durable glass architecture, this USA-style tube contains highly purified helium element gas and comes equipped with sealed metal electrodes placed carefully at both ends. When illuminated via a matched induction coil spark or a standard laboratory power supply, the energized helium gas generates a brilliant illumination that exhibits a unique, recognizable set of spectral lines when viewed through a spectroscope. Users can also implement a diffraction grating component to clearly show off the emission spectra during physics, chemistry, or astronomy demonstrations. Measuring approximately 10.25" x 0.5" x 0.8" in tube dimensions, this non-toxic glass assembly delivers a perfectly calibrated teaching instrument recommended for adult use only.
