Potassium Metal Element Sample 15mg Micro Ampoule 99.99% Pure - Periodic Table

Description

This listing is for
a
15mg ampoule of Potassium metal sealed under argon.  Purity is 99.99%.
The metal inside is shiny and oxide free but
the yellow color is due to the color of the glass itself.
These will fit nicely inside a 5/8dram vial and one will be included with every purchase.
They are the perfect size for collectors who want a small sample of this reactive metal.
This sample must ship UPS ground only.  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 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.
