Kinexus is a rotational rheometer system that applies controlled shear deformation to a sample under test, to enable measurement of flow properties (such as shear viscosity from flow tests) and dynamic material properties (such viscoelastic modulus and phase angle from oscillation tests).
A rotational rheometer system comprises several key components to enable robust, reliable and accessible rheological measurements for a particular sample or application:
Control of key system functions, including torque (for stress control), rotational position change (for strain or rate control), normal force and vertical position change (for sample loading and gap set).
The measuring system is the link between the rheometer and the sample, and defines the applied shear field. The type of measuring system must be appropriate to the sample type and the test under consideration.
Accurate control is essential since rheological properties are a strong function of temperature and environmental conditions.
