This power supply is designed to safely operate spectrum discharge tubes and provide clear visibility of gas emission spectral lines. It supports a wide range of instructional activities—from simple observations using a diffraction grating to advanced analysis with spectrometers. Studying these spectra is foundational across middle-school science, high-school chemistry and physics, and university courses in chemistry, physics, and quantum mechanics. Students gain hands-on understanding of discrete energy levels demonstrated by illuminated gas tubes. A classic application with this power supply is determining and measuring the Balmer Series of Hydrogen. Multiple gas tubes—such as hydrogen, helium, nitrogen, neon, carbon dioxide, argon, xenon, iodine vapor, oxygen, air, and krypton—are compatible. Spectrum tubes are not included.
Features • Accommodates 26 cm spectrum tubes, producing emission lines suitable for spectrometer analysis (tubes and spectrometers not included). • Spring-loaded, shielded tube sockets enable easy insertion and removal while enhancing user safety. • Flat black exterior minimizes ambient light interference for accurate spectral observation. • Integrated on/off switch with pilot light. • Main operated 220V AC @ 50/60 Hz , Supplied with power cord.
