Helium
Atomic no.:
2
Atom. weight: 4.002602
Density: 0.17847
Class:
Gas

A colourless, odourless gas that is totally unreactive. It is extracted from natural gas wells, some of which contain gas that is 7% helium. It is used in deep sea diving for balloons and, as liquid helium , for low temperature research. The Earth’s atmosphere contains 5 parts per million by volume, totalling 400 million tonnes, but it is not worth extracting it from this source at present.

NEW!  Super bright Helium 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. 

 

ou can easily let it glow with a tesla generator.

Lengh: 10cm, dia. ~12mm

Operating voltage 5000V @ 20mA - available here in our shop
