Highest specification rheometer bearing system
The Kinexus ultra+ rheometer has the highest sensitivity air bearing and widest torque range, coupled with the unprecedented vertical (axial) control capabilities of the Kinexus platform, for advanced rheological testing. Unique sequence-driven rSpace software enables fully customizable test design to allow researchers to set-up and investigate tailored rheological test protocols.
The Kinexus ultra+ rheometer incorporates technological innovations that enable optimal flexibility in rheological test capabilities and protocols - for advanced research.
- All modes of rheological operation – stress control, shear rate control and direct strain controlled oscillation at demand strain amplitude for accurate control of sample strain history.
- Unprecedented dual-action capabilities for both shear and vertical testing.
- Highest specification air bearing with ultra-low torque offset to minimise data corrections.
- Exceptional vertical travel and gapping capabilities with ultra-responsive and highly sensitive normal force system for class-leading performance.
- Unique rSpace software interface that offers total flexibility of test set-up - from fully customizable test design for new and advanced research capabilities to sequence-driven Standard Operating Procedure (SOP)-type functionality.
- Wide variety of measurement geometries optimized for rheological characterization of complex fluids and soft solids, including dispersions, emulsions, polymer and surfactant solutions, pastes and gels.
- Intelligent geometry recognition with full auto-configuration and user feedback on system status to guarantee robust data for all measurements.
- Complete sample history from the point of loading onto the rheometer available in data file as standard – because ensuring reliable rheology data for complex non-Newtonian materials actually starts before a measurement takes place.
- Unique ‘plug and play’ cartridge system for all temperature and environmental controllers – all mechanical, power, communication and fluid connections made in one simple action.
- Multifunctional accessory design – plate cartridges with interchangeable lower plates for a cost-effective solution addressing the widest application coverage.
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:
- Rheometer base unit. 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).
- Measuring system or geometry. 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.
- Temperature or environmental control unit. Accurate control is essential since rheological properties are a strong function of temperature and environmental conditions.
- Instrument software. Rheological testing can be, by its nature, relatively complex to set up. Malvern Panalytical’s cornerstone Standard Operating Procedure (SOP) approach to material testing has been enhanced in rSpace software to revolutionize and simplify user interaction, and to bring ‘expert system’ guidance and SOP-driven testing to rheological measurements for the first time.
Understanding the application under consideration, and the associated rheological test requirements, is a key factor in selecting the most appropriate rheometer system.
