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
