Abstract: Microcalorimetry apparatus that includes structure defining a chamber, thermal insulation enclosing the chamber, and a plurality of sample support structures in the chamber. Each sample support structure includes a thermally insulated receptacle for receiving a sample to be analyzed, a sensor for sensing a sample container disposed therein and providing an output signal indicative thereof, and a temperature sensor disposed for sensing a change in temperature of the sample in the receptacle. One wall of the chamber has a plurality of spaced ports therein, each port being aligned with a corresponding sample support structure and permitting introduction and removal therethrough of a sample from the receptacle of the corresponding sample support structure. The apparatus also includes a plurality of sample container handling structures, each such structure including sealing structure for sealing a port in the wall and coupling structure for detachable connection to a sample container for inserting the sample container through the port for positioning in the receptacle with the sealing structure concurrently sealing the port. Each sample container includes a cylindrical body portion and a radially projecting cylindrical surface above the body portion which actuates the sensor when the container is disposed in the receptacle.
