Claim 0:
1. A method for determining the density of an at least flowable or liquid specimen, the method comprising:
providing a rotational rheometer including a first measurement component for receiving the at least flowable or liquid specimen, and a second measurement component to be immersed into the specimen, the first measurement component and the second measurement component each having a bottom surface, the components being movable relative to one another and the second measurement component having a known volume;
measuring a normal force acting in a direction normal to the rheometer between the bottom surfaces of each of the first and second measurement components after an immersion of the second measurement component into the specimen, the measured normal force corresponding to a buoyancy force acting between the specimen and the second measurement component; and
calculating the density of the specimen based on Archimedes' principle by reference to the known volume of the second measurement component and to the measured normal force.
