The isotope krypton 86 has a line in its atomic spectrum that is now the standard measure of length : 1 metre is defined as exactly 1,650,763.73 wavelengths of this line.

NEW!  Super bright Krypton spectrum discharge tube 100mm - NEW

This new discharge tube is 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. 

 

You can easily let it glow with a tesla generator.

Lengh: 10cm, dia. ~12mm
