NEW! Oxygen O2 – Micro Spectrum discharge tube – metal free!
This new spectrum discharge tube is an enhancement of our gas ampoules with all its benefits not having any metals parts but the luminosity of a standard spectrum tube. This tube can be used in continuous operation!
Made of high quality shock- and heat proof boro silicate glass. The fine capilary looks fragile but is more endurable as any normal tube.
You can easily let it glow with a tesla generator.
Lengh: 3.3 – 3.5″ = 8 – 9cm, dia. ~12mm
Operating voltage 1500-5000V @ 20mA – available here in our shop
This is a very special piece for a complete elements collection !!!
