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.
  • Rapid temperature changes of up to 30°C per minute.
  • Extremely stable temperature control using a high accuracy PT100 sensor in close proximity to sample.
  • Temperature resolution to 0.01°C.
  • Wide range of compatible cone-plate and parallel plate measuring systems available as standard.
  • Interchangeable lower plates enable optimal geometry choice for particular samples, whilst maintaining optimum thermal performance.
  • Easy to clean design.
  • Efficient solvent trap design for accurate measurement of samples with volatile components and to minimize sample drying over long times.
  • Disposable plate option for curing materials.

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.
