Abstract
A rotational rheometer has a cylindrical outer housing into which a measuring container can be inserted substantially coaxially thereby forming a radial annular space. The measuring container has a measuring chamber for receiving a sample material. A fluid may flow through the annular space to bring the outside of the measuring container and thereby the sample material to a desired temperature. The fluid is a gas and a circulating device is provided within the outer housing for circulating the gas.
