The General Purpose Rocket Furnace provides three independently controlled cavities for melting and resolidifying experimental specimens in a microgravity environment. Each cavity can be operated to provide near-isothermal or gradient temperature profiles. Samples can be cooled at specified rates with a cold gas quench through a common manifold or water-cooled heat sink integral with each cavity while maintained in a sealed atmosphere.
