Discoverer: Gheorges Urbain
Place: Paris, France
Year: 1905

Discovered in 1907 by G. Urbain in Paris, France, and, independently, by C. James at the University of New Hampshire, USA. Lutetium is the hardest, densest and one of the rarest of the lanthanide group of elements (it has an abundance of 0.51 ppm in the earth's crust). It is found in some of the less common minerals (e.g. gadolinite and xenotime) and is difficult to isolate. Applications of lutetium tend to be limited to research only.

As professional producer and seller of chemical element samples for science and education we are able to offer you:
  • Surfaces are mechanically cleaned and oxidations removed
  • We do not fill any crumbs, filings or other low value material but ONLY carefully hand-selected pieces!
  • glass-ampoules are carefully cleaned and dried by a special process for several hours to remove even the slightest traces of humidity to make the samples last a life-long.
  • We use shatter-proof tempered glass, which are able to survive a 1 meter drop on a tiled floor.
  • Some elements like Europium, Lanthanum and Cerium are handled and filled under very dry and oxygen free atmosphere in a glove-box to keep the surface as shiny as possible.
  • lifelong warranty on breakage - should an ampoule break accidentally we replace it for free!
