About This Product
Comparing the line spectra of several gases shows students that each element has a pattern of its own, which leads naturally into electron transitions and atomic energy levels. The tubes are changed one at a time with the unit switched off. Laboratories and colleges in Venezuela, Kyrgyzstan, Paraguay, Equatorial Guinea, Mauritania and Laos can buy the Spectrum tubes kit, with power unit through an export order.
