Super bright Series

Super bright spectrum discharge tubes!
These new discharge tubes are a redevelopment of our luminescent ampoules and offers the benefits of a metal-free ampoule with the luminosity of a commercial spectrum tube. In this tube, the excited gas has to pass through many small capilaries and is forced to particularly strong shine. Good contact between the external electrodes around the ampoule is required.
Made of high quality shock- and heat proof boro silicate glass.
