- High-temperature measurements up to 400 °C
- Parallel-plate, cone-plate, concentric cylinder, and double-gap measuring geometries
Accurate temperature control is crucial for rheological testing, as all materials exhibit temperature-dependent rheological behavior. Electrically heated temperature control units are primarily used for high-temperature rheology measurements of polymer melts, hotmelts, and curing materials such as resins or epoxy. These systems feature high heating and cooling rates as well as excellent temperature accuracy and stability.
Key features
Fast and accurate temperature control from -150 °C to +400 °C
Electrical temperature control by Anton Paar is an approved heating technology which enables heating rates up to 50 °C/min to minimize the waiting time before a desired measurement temperature is reached. By default, the accessible temperature ranges from room temperature up to 400 °C. Active cooling and heating are available to reduce cool-down time and increase measurement throughput. In combination with a low-temperature option based on liquid nitrogen or a gas chiller unit, temperatures down to -150 °C and cooling rates up to 100 °C/min can be reached. An actively heated hood minimizes undesired temperature gradients within the sample and enables flushing with inert gas to prevent degradation during testing. The hood features a sliding rail for easy access and sample trimming. Shaft cooling ensures a cool measuring geometry and prevents overheating.
Flexibility and error-proofing
The systems provide electrical temperature control for parallel-plate, cone-plate, concentric cylinder, and double-gap measuring geometries. For special tasks, stirrers and vanes can also be used (e.g., for samples containing large particles). Quick connectors for cooling media and a connection to the MCR rheometer ensure fast and easy mounting within seconds. The temperature devices work in combination with Anton Paar’s proven MCR rheometer technology. To prevent measuring errors, the Toolmaster function automatically recognizes and configures the connected temperature devices and measuring geometries. XL versions with increased sensitivity for measuring liquids with very low viscosities (e.g., water or solvents) are also available.
Additional accessories for special tasks
For special measurements, Anton Paar offers inset versions for exchangeable lower plates in various diameters and materials. Disposable cups and plates are available to avoid cleaning of sticky samples or for high-throughput sample preparation. Measuring geometries with different kinds of surfaces, such as roughened or sandblasted, are designed to meet sophisticated measuring requirements (e.g., to prevent wall slip or to characterize curing reactions). Electrical temperature control devices can be combined with solvent traps to prevent evaporation or drying of samples (for coatings, paints, and food rheology). Pressure cells are also available as accessories for measurements under elevated pressure. All measuring geometries are produced in-house to achieve Anton Paar’s standards of robustness, high durability, and reliability – ensuring minimal downtime and low service costs.
Advanced material characterization
In addition to standard electrical temperature devices, Anton Paar offers modular systems that can be combined with rheo-microscopes, small-angle light scattering systems, polarized imaging options, a Raman spectrometer, and self-designed optical accessories. These enable simultaneous insights into both the smallest microstructure changes in a sample and the macroscopic “big picture.” The temperature control unit, which covers a temperature range from room temperature to 300 °C (and even higher on request), can also be combined with a UV light option for rheological characterization of UV-reactive samples.
