• Commonly used in physics and chemistry education, this spectrum tube provides clear demonstrations of electron excitation, photon emission, and the relationship between atomic energy levels and emitted light.
• Each tube is individually labeled with the gas symbol and securely packed in foam-protected triangular cartons, ensuring safe transport and storage for classroom or laboratory use.

The GSC International 1865-4 Hydrogen Spectrum Tube is a high-quality teaching tool designed to demonstrate the emission spectrum of hydrogen. Constructed from 26 cm borosilicate glass, the tube is sealed with low-pressure hydrogen gas and emits a clear spectrum when connected to a high-voltage power supply such as the 1865-PS.

The hydrogen spectrum reveals the Balmer series lines, including the visible red (H-alpha), blue-green (H-beta), and violet (H-gamma) lines, which are essential for studying atomic structure and electron transitions.
