Abstract: An instrument and associated method are disclosed for performing microwave assisted organic chemical synthesis at low temperatures. The instrument includes a reaction vessel formed of a microwave transparent material that defines an interior reaction chamber for carrying out microwave assisted reactions in the chamber, a cooling jacket immediately surrounding the reaction vessel for cooling the vessel and the vessel contents during the application of microwave energy to contents in the vessel when a microwave transparent media used as a fluid coolant is present in the jacket. The instrument includes means for supplying a microwave transparent fluid coolant to the cooling jacket and means for venting the fluid coolant from the cooling jacket, a fluid coolant reservoir in communication with the cooling jacket, and a pump in communication with the reservoir and the cooling jacket for circulating fluid coolant from the fluid coolant reservoir through the cooling jacket and around the reaction vessel.
