Spectrum Tube Air

Mixed emission spectrum for atomic structure labs

The Air Spectrum Tube contains a mixture of gases and produces a complex emission spectrum, making it ideal for demonstrating real-world spectroscopy. Unlike pure gases, air displays overlapping spectral features that help students understand why natural light sources often produce composite spectra. A classic atomic theory demonstration that introduces authentic analytical challenges.

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 Air Spectrum Tube

• Real-world relevance: Demonstrates why natural spectra are complex rather than perfectly discrete.
• Encourages critical thinking: Students must interpret overlapping lines instead of matching a simple “fingerprint.”
• Ideal comparison tool: Works well alongside pure gases to contrast mixed vs. elemental spectra.

Standard compatibility: 26 cm length fits many common spectrum tube power supplies.
