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 

We ship osmium with full-cream milk powder, in case of breakage. Full-cream milk powder will inactivate osmium tetroxide's toxic vapours and is less messy than corn oil
