Diffusive Mixing of Organic Solution (DMOS)

DMOS, or Diffusive Mixing of Organic
Solutions, designed to grow crystals through the combination of organic
solutions. DMOS was flown on orbiter Discovery in November 1984. Under the
supervision of Cleave, the DMOS apparatus will build six types of organic
crystals for 3M. These crystals will be larger and more pure than those grown
in a positive gravity environment.
