A rheometer is a kind of viscometer that measures visco-elastic properties of materials beyond just viscosity. Rheology is the flow of fluids and deformation of solids under various kinds of stress and strain. This tool, therefore, measures material behavior such as yield stress, kinetic properties, complex viscosity, modulus, creep, and recovery.

Kinexus Pro+


       Research grade rheometer for complex fluids characterization

       The Kinexus pro+ rheometer incorporates technological innovations that enable optimal flexibility in rheological test capabilities and protocols - for research and development requirements.

  • 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.
  • 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 sequence-driven Standard Operating Procedure (SOP)-type functionality to fully customizable test design for new and advanced research capabilities.
  • 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.






Model: Rosand RH7/10


       Robust research capillary rheometers for high force conditions.

       Research-level Rosand RH7 and RH10 capillary rheometers provide highly flexible measurement capabilities for materials under high pressure and high shear rate extrusion - from polymer melts to ceramics, and from foodstuffs to inks and coatings.

  • High force range (up to 100kN) and wide dynamic speed range (>225,000:1) allow test correlation with real material processing conditions.
  • Twin bore barrels as standard enable absolute shear viscosity measurements and simultaneous calculation of extensional (elongational) viscosity.
  • Range of optional barrel sizes and barrel materials to permit measurement of thermally-sensitive, chemically-aggressive or aqueous-based samples.
  • Wide range of high precision tungsten carbide dies as standard to cover all materials and test types.
  • Easily interchangeable melt pressure transducers to cover all test requirements – configured with low noise, triple-stage amplifiers for optimized measurement sensitivity at the die entry when using ‘zero length’ dies (extensional viscosity measurements).
  • Nitrogen purge option available for testing in a dry, inert atmosphere to minimize sample degradation.

       Integral fume chamber with extraction to vent sample gases for operator safety.

  • Proprietary bi-modal speed control algorithms suited to low and high speed operation optimize shear rate measurement range for a particular die.
  • Precise sample temperature control using three independent zone heaters, with 10 times DIN accuracy platinum resistance thermometers. High temperature (500 degree Celsius maximum) and cooling coil options also available.
  • Rigid ‘H’ frame design for compliance-free measurements in transient tests such as pVT determination.
  • Open design below barrel exit to accommodate optional accessories such as die swell measurements, melt cutters, slot die system and melt strength (Haul Off).
  • Easy to use Flowmaster software with full range of tests and analyses for shear and extensional viscosity, as well as determining sample stability, wall slip and melt fracture.
