This classroom set of spectrum tubes allows each student to observe the colored spectral lines of 10 different compounds. By placing a small amount of a compound in a flame, a distinctive color is produced. Viewing the colored flame through the spectrum tube shows each chemical's distinctive "fingerprint" as a series of differently colored bright lines. The students can assemble their own spectroscopes and use them to compare a variety of other light sources such as incandescent bulbs, fluorescent tubes, and neon lights.

Student Grade Spectrum Tube. Used for demonstration.The classic demonstration of spectral lines. Each tube has its characteristic spectrum when energized before a spectroscope. Ideal for acquainting students with the spectra of better known gases in their pure form and for wavelength determination. The glass tubes are 25cm long with the capillary portion about 10cm long. An electrode is sealed in each end and attached to a metal end cap with a loop for convenient hookup to wire connections. Recommended for use with our Spectrum Tube Power Supply
