Several types of rheometers are employed to study catalytic systems, including:
Rotational Rheometers: These measure the torque required to rotate a sample at a controlled shear rate or shear stress. Capillary Rheometers: These determine the flow properties by forcing the sample through a narrow capillary and measuring the pressure drop. Oscillatory Rheometers: These apply oscillatory shear deformation to measure viscoelastic properties, which is particularly useful in studying complex fluids.
