These tubes are ideal for acquainting students with the spectra of better known gases in their pure form and for wavelength determination. -- The glass tubes are 25 cm long with the capillary portion about 10 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. -- Spectrum tube assemblies can be used in a variety of spectroscopic applications. When observed through a spectroscope the emission lines corresponding to the energy transition levels of the gaseous atoms or molecules will appear as distinct components. -- These research grade tubes are specially designed to provide optimum intensity and line resolution. Recommended for use with our Spectrum Tube Power Supply (62999-26). |
