Environmental controllers for the Kinexus rheometer are based on a unique ‘plug and play’ cartridge design.

  • Cartridge insertion mechanism is quick, easy and robust.
  • All mechanical, power, communication and fluid connections made in one action.
  • Automatic cartridge recognition and configuration.
  • Twin Peltier design for rapid temperature changes and sample equilibration, and minimized thermal gradients.
  • Temperature resolution to 0.01ºC.
  • Various cup and bob sizes available - C14 (DIN), C25 (DIN) and wide diameter C34.
  • Double gap cell for high sensitivity measurements with low viscosity fluids.
  • Range of vane tools available for characterizing dispersions, including yield stress materials.
  • Interchangeable lower cups to optimize measurement set-up for different sample types, plus removable base options for ease of cleaning.
  • Can be used with Torsion/DMA system to allow testing of a self-supporting rectangular or cylindrical solid sample.
  • Additional plate insert provides a ‘universal Peltier option’ which enables the rheometer to be used in either coaxial cylinder or plate measurement mode with one cartridge.
  • Additional optical plate insert provides an optical path for imaging of a sample during measurement.  
  • Can be configured for use with the UV/Visible Curing System 

Accurate temperature measurement and control is a fundamental requirement for almost all rheological measurements. The Kinexus rheometer uses easily interchangeable environmental controllers based on a unique cartridge design, to meet temperature control requirements for a variety of complex fluids and soft solid samples.

Peltier-based temperature control units use solid-state thermoelectric Peltier modules as heat pumps, to control the temperature of the sample.

Peltier systems have benefits which make their use advantageous for rheometer temperature control – having high heating and cooling rates, and providing excellent temperature accuracy and stability.

The use of a separate heat exchanger system, to remove excess heat from the Peltier module to maintain its optimum working efficiency, is a general requirement when used for temperature control on a rheometer system. 

If you are unsure as to specifying an appropriate temperature and environmental control unit for your sample type or measurement application, please contact Malvern for further advice and/or a sample test and evaluation report.
