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

This Argon Spectrum Tube is ideal for KS5 physics and chemistry, providing a bright, detailed demonstration of the emission spectrum of argon gas. Constructed in a straight‑form design, the tube measures 260 mm in length and features a 50 mm fine capillary section, enhancing the brightness and clarity of argon’s characteristic violet, red, and blue emission lines when energised.

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

This argon‑filled tube is a valuable tool for teaching atomic structure, electron transitions, quantised energy levels, and spectroscopy, allowing students to compare argon’s unique spectral lines with those of other noble gases.
