Spectrum Tube – Hydrogen (Straight Form, 260 mm, KS5)

This Hydrogen Spectrum Tube is ideal for KS5 physics and chemistry, providing a clear and bright demonstration of the emission spectrum of hydrogen gas. Designed in a straight‑form style, the tube measures 260 mm in length and includes a 50 mm fine capillary section, which enhances the sharpness and visibility of hydrogen’s distinct spectral lines—including the well‑known Balmer series—when energised.

For safe and effective operation, this spectrum tube should be used with a Spectrum Tube Holder with Power Supply, ensuring correct electrical connection, stability, and appropriate shielding during classroom demonstrations.

This hydrogen‑filled tube is perfect for advanced lessons exploring quantum theory, electron transitions, energy levels, and the historical development of atomic structure through spectroscopy.
