NexGen Spectrum Tube Classroom Bundle

The NexGen Spectrum Tube Classroom Bundle offers a safer power supply that runs eight gas spectrum tubes (included). Seamlessly switch from one gas to another by sliding the polymer-enclosed spectrum tubes out of the energizing slot and sliding the next one in. The NexGen Spectrum Tube System offers a considerable improvement in safety, convenience, and tube life over conventional systems. Conventional spectrum tubes require a "30 seconds on, 30 seconds off" power cycle, but these "electrodeless" tubes does not have that limitation. This feature lets students take their time measuring spectral emissions. Unlike other designs, the system has no exposed high voltage to eliminate the risk of electric shock, and the built-in magnetic interlock system prevents the spectrum tube from being energized unless the tube is correctly inserted. Spectrum tubes that have not been energized for an extended period of time may not strike right away. It is normal for the tube to take up to 3 minutes to strike for the first time.  Please note, make sure to turn the power switch off before removing or exchanging tubes.
