 22,90

Availability: Available on backorder

SKU: 04574 Categories: , ,

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.
