Explore argon's rich spectrum of violet and red lines
The NexGen Spectrum Tube, Argon is a gas discharge tube filled with argon gas for use with the NexGen Spectrum Tube Power Supply. When powered, it produces a blue-violet to lavender glow. Through a spectroscope or diffraction grating, that glow resolves into dozens of distinct emission lines spread across the visible range, with notable concentrations in the red and violet regions.
Argon is the third most abundant gas in Earth's atmosphere and a common fill gas in incandescent bulbs and double-paned windows. In the classroom, its spectrum offers something the simpler noble gases don't: a dense collection of visible lines that fills the field of view of a spectroscope. That density makes argon a useful reference gas and a clear demonstration that each element carries a characteristic, identifiable optical signature, with no two elements producing the same pattern.
Why Teachers Love It
Dense Spectrum Ideal for Spectroscope Practice – Argon produces far more visible lines than helium or hydrogen, giving students plenty to measure and map. Comparing argon's complex output to a two- or four-line element shows how an atom's electron configuration determines the richness of its spectrum.
Built for Long-Term Classroom Use – No internal electrodes means the tube resists the wear that shortens conventional spectrum tube life. A hard polymer shell protects the glass from everyday bumps and drops.
Continuous Use with the NexGen Power Supply – No timing restrictions. Students read and record spectral line positions at their own pace without a 30-second on/off cycle.
