Targeted at the rheological characterization of dispersions and other complex fluids and soft solids, the Kinexus pro+ rheometer has unprecedented dual-action capabilities for both shear and vertical testing. A modular rheometer with true ‘plug and play’ functionality for all measuring systems and environmental control units, Kinexus also enables pioneering Standard Operating Procedure (SOP) driven rheological testing.
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:
