Helium emission spectrum for atomic structure labs

The Helium Gas Spectrum Tube contains helium gas and produces bright, well-defined emission lines that clearly demonstrate how excited helium atoms emit light at specific wavelengths. Helium’s distinctive line spectrum makes it an excellent example for exploring atomic structure, electron energy levels, and the behavior of multi-electron atoms—an important step beyond hydrogen. A classic atomic theory demonstration widely used in spectroscopy labs.

Designed for classroom spectroscopy, this 26 cm gas discharge tube fits standard spectrum tube power supplies and is widely used across physics, chemistry, astronomy, and forensic science labs.

Why Teachers Love the Helium Spectrum Tube

Clear, recognizable spectrum: Helium produces a rich set of bright emission lines that are easy for students to observe with any spectroscope.
Extends atomic theory beyond hydrogen: Ideal for comparing single-electron and multi-electron atoms.
Compatible with standard equipment: 26 cm length fits many common spectrum tube power supplies.
Cross-disciplinary relevance: Used in physics, chemistry, astronomy, and forensic science instruction.

What You Can Teach with the Helium Spectrum Tube

Use in high school and introductory college courses to teach:

Atomic emission spectra: Observe discrete wavelengths emitted by excited helium atoms.
Electron energy levels: Connect spectral lines to quantized electron transitions in multi-electron atoms.
Comparative atomic structure: Contrast helium’s spectrum with hydrogen and other gases.
Wavelength–color relationships: Relate observed line colors to specific wavelengths of light.
Astronomy applications: Model how helium spectra are used to study stars and stellar evolution.

Works With the Spectrum Tube Power Supply

Pair the Helium Spectrum Tube with Arbor Scientific’s Spectrum Tube Power Supply to safely energize the gas and produce clear, stable emission lines. The power supply is designed specifically for 26 cm spectrum tubes, providing the correct voltage and current for reliable classroom demonstrations.
