Your cart is empty.The classic demonstration of spectral lines. Each tube has its characteristic spectrum when energized before a spectroscope. These tubes acquaint students with the spectra of common gasses in their pure form, as well as for demonstrating wavelength. 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. Each spectrum tube includes an activity guide.

It is a bit too thin in the center and I broke it. Since it did not have toxic chemicals I did not complain as I broke it by accident it was my own fault. I threw the glass away as it was all over the floor and had to be cleaned up. I did get some nice color with it from a little experiment.
