Spectrum Tubes demonstrate the wave properties of different gases.

• Ideal for Wavelength Determination
• For Introducing Students to Better-Known Gases
• Glass Tube Length: 10"
• Capillary Portion Length: 4"
• Tubes Work in a Variety of Spectroscopic Applications

Ideal for wavelength determination and introducing students to the spectra of better-known gases, these glass tubes are 10" long, and the capillary portion is about 4" long. The spectrum tube assemblies can be used in a variety of spectroscopic applications.

When they are observed through a spectroscope, the emission lines corresponding to the energy transition levels of the gaseous atoms or molecules appear as distinct components. The Spectrum Tube Power Supply is required but not included.
