Abstract:
1. A rheometer having a rotatable shaft ( 1 ) on which a rotor plate ( 2 ) is fastened, and having a measuring instrument ( 10 ) for measuring torques exerted on the rotor plate ( 2 ) by a substance ( 6 ) to be studied during rotation of the shaft ( 1 ), wherein a first measurement gap ( 5 ) for holding the substance ( 6 ) to be studied is formed between a first side ( 3 ) of the rotor plate ( 2 ) and a first shear face ( 4 ) and a second measurement gap ( 9 ) for holding the substance ( 6 ) to be studied is formed between a second side ( 7 ) of the rotor plate ( 2 ), opposite the first side, and a second shear face ( 8 ), and wherein the rheometer contains a magnet for generating a homogeneous magnetic field in the first and second measurement gaps ( 5 , 9 ).
