Spectral Tube Power Supply and Mount
This system is easy-to-use and inexpensive, with a variety of safety features that make it suitable for beginning labs. Mount any of the 8 different spectral tubes into the power supply and turn it on. The 26 cm long tubes are capillary-thin over the middle 10 cm, providing sharp, bright spectra.
Features :
Student Safety : The tubes mount from the front of the supply and snap into moulded sockets that fully enclose the conductive ends. The all-metal case is electrically grounded. Spectral Tube Safety : A current limiting transformer protects the tubes. A protective shield also helps safeguard the tubes, while blocking unwanted ambient light for clear viewing. Power requirements : 220 VAC, 50 Hz
