Fann Model 35SA Viscometers are true Couette coaxial cylinder rotational viscometers. With this type of viscometer the sample is confined between two concentric cylinders, one of which, the rotor, is rotated at a constant velocity. The rotation is the rotor in the presence of the sample produces a torque that is measured at the wall of the inner cylinder. The cylinder radii are such that the sample is homogeneous and the shear-stress is as uniform as possible across the gap.
