United Scientific™ Spectrum Tube

Investigate the spectral pattern of different gases.

• Ideal for classroom demonstrations of spectral lines
• Glass tube is 25 cm long, with 10 cm long capillary portion
• Electrode sealed in each end, attached to metal end cap with loop for convenient hookup to wire connections

Air spectrum tube for classroom demonstrations of spectral lines. Spectrum tubes acquaint students with the spectra of common gases in their pure form, and are also used for demonstrating wavelength. Each gas has its own distinctive set of spectral lines when energized and viewed through a spectroscope.

Glass tube measures 25 cm long with the capillary portion about 5 cm long. An electrode is sealed in each end and attached to a metal end cap with a loop for convenient hookup to wire connections.

 : A spectrum tube power supply (not included) is required to energize the tube.

 : Includes an activity guide.
