The Kinexus lab+ was developed for the requirements of a QC laboratory to ensure reliable rheological tests. Ease of use is paramount. The rSpace software enables rheological tests via standard operating procedures (SOPs) and test protocols that can be used company-wide.
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:
