Excitation of the gas in the tube produces light
Spectrum Tubes are an effective tool to teach the effect of gas excitation and visible light emission. Our Spectrum Tubes can also be used together with the Spectrometer (code 4455.02) to analyse the spectra of gases in the different tubes.
Spectrum Tubes can easily be mounted on our Tube Holder that protect them against accidental shocks. Tubes of different gas types are available. They are designed to be capillary thin at their centre point to produce a sharp and bright spectra.
