Small size (2 ml), Light-gauge, pre-scored amber glass ampoules. 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.

Osmium is a highly toxic, volitile solid, crystalised compound.  It is colourless but almost appears yellow. 

Aqueous Solutions are sealed under dry nitrogen with exact concentrations and volume in pre-scored amber-ampoules.

Applications:

It has many uses with most common being a post-fixative in EM.
