This power supply provides safe and reliable operation for 10 spectrum tubes. The unique design supplies a voltage that prolongs the life of the spectrum tubes. Specially designed sockets eliminate electrical shock hazards. CE approved, universal plug i..

Use for the classic demonstration of spectral lines. Each tube has its own characteristic spectrum when energized before a spectroscope. This tube acquaints students with the spectra of common gases in their pure form as well as for demonstrating wavele..
