Refrigerators used for storage of flammable chemicals must be explosion-proof, laboratory-safe units. Materials placed in refrigerators should be clearly labeled with water-resistant labels. Storage trays or secondary containers should be used to minimize the distribution of material in the event a container should leak or break. It is good practice to retain the shipping can for such secondary containers. 

Powders milled in solvents were either dried in trays using a forced air explosion proof dryer or in a rotary evaporator. Dried cakes were then granulated by screening through an 80 mesh nylon screen.
