Calcium Metal Element Sample 5g Distilled Crystals in Ampoule 99.99% Pure

Description

This listing is for
a 5g sample of Calcium metal in the form of beautiful distilled crystals under argon.  Purity is 99.99%.
Calcium metal is almost never encountered in this form and will remain shiny forever.
Photos just don't do this sample justice.
I also have several other crystalline metal samples in ampoules listed as well.  This would make a great addition to someones element collection. Please check my other listings for more element samples. Looking for an element you don't see listed? Feel free to contact me through ebay because I can get almost anything.
I have Na metal, K metal and Li metal available as well. I also have samples like As metal, Tl metal, Hg metal, White P, Br, Rb and Cs. Please don't hesitate to contact me through ebay if interested and I can create a custom listing for you. Thanks for looking.
