Osmium tetraoxide

Small size (2 ml), light-gauge, pre-scored amber glass ampoules containing OsO₄ crystal, are pre-cleaned and heat sealed in plastic bags to assure a contaminant-free solution.


Ampoules are also free of pressure-sensitive labels and, therefore, do not require cleaning prior to solution preparation.
