Abstract
A self venting sealable vessel system for microwave assisted chemistry is disclosed. The system includes a vessel formed of a microwave-transparent material, one end of which forms an opening for placing materials inside the vessel, a lid for being seated against the opening, a flexible frame surrounding the vessel and lid and formed of a microwave-transparent material, and means for urging the frame against the vessel and seated lid with a predetermined force to seal the vessel at low pressures and so that the frame refrains from flexing until the pressure inside the vessel exceeds the predetermined force, after which the frame flexes sufficiently to allow the lid to unseat and gases to vent safely from the vessel without rupturing the vessel or the frame.
