ABSTRACT:
A pressure and temperature reaction vessel is constructed from substantially microwave-transmissible materials. The vessel includes pressure-relief vents and a sliding seal which isolates a pressure reaction chamber from the vents. A visual indicator is operatively associated with the sliding seal to indicate pressure within the reaction chamber. At pressures above a preselected limit, the sliding seal becomes unsupported and the reaction chamber is fluidly communicated with the vents.
