A method for determining the density of an at least flowable, in particular liquid, specimen with a rheometer, in particular a rotational rheometer, includes providing the rheometer with a first measurement component for receiving the at least flowable, in particular liquid, specimen, and a second measurement component with a known volume to be immersed into the specimen. The first and second measurement components are movable relative to one another. The perpendicular force between the two measurement components is measured after the immersion of the second measurement component into the specimen. The measured perpendicular force corresponds to the buoyancy force acting between the specimen and the second measurement component. The density of the specimen is calculated based on Archimedes' principle by reference to the known volume of the second measurement component and the measured perpendicular force. A rheometer for carrying out the method is also provided.
