3D3D25ml zirconium crucible.
This is a brand new 25ml (little under one fluid ounce) solid zirconium laboratory crucible. While more expensive than common stainless steel or ceramic crucibles, these are a whole lot cheaper than the next grade up, platinum. The goal of a crucible is to withstand high temperatures and corrosive contents without adding any contamination to the material being heated. In this regard zirconium is quite good, but of course not as good as platinum (otherwise why would they ever use platinum at 50 times the price?).
