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

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

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

Applications: 
Many uses, most commonly a post-fixative in EM.   

 
Storage:  
Store at room temperature 

Store with milk powder - full-cream milk powder will inactivate osmium tetroxide's toxic vapours and is less messy than corn oil
