Temperature Control:
Convection Temperature Devices (-160 °C to +1000 °C)

Control the greatest influence of all

The convection temperature devices enable control of the greatest rheological influence of all: temperature. Users benefit from an enormous temperature range to meet specific sample requirements. At the same time, the design allows use of almost every measuring system in the extensive MCR accessory portfolio, from parallel-plate systems (including disposable systems) to dynamic mechanical analysis in torsion or extension. Controlled relative humidity can also be applied to the sample in combination with temperature. Users can rely on the high-precision temperature control required for truly accurate results in all kinds of rheological tests.

The most innovative production techniques

State-of-the-art production techniques such as 3D metal printing take temperature control to the next level. The unique design of the inner shells of the CTD 600 MDR convection temperature device – each manufactured as one piece – ensures an absolutely homogeneous temperature distribution within the oven. With CTD 600 MDR, temperature gradients are a thing of the past. Additionally, only low gas flow rates are needed, minimizing unwanted effects on measurements due to air vortexes or drying samples.

Extensive MCR accessory portfolio

A wide range of applications require flexible temperatures, measuring systems, and testing solutions. In addition to standard measuring systems, solutions made of Inconel, graphite, or other temperature- and corrosion-resistant materials allow characterization of a broad variety of samples and even high-temperature materials (e.g., metals, salts, glass). Beyond rheological measurements and dynamic mechanical analysis, convection temperature devices enable powder rheology , tribology , and liquid density measurements up to very high temperatures. Anton Paar’s CTD 1000 MDR can be combined with a lower linear drive to perform dynamic mechanical analysis in tension, compression, and bending  up to 1000 °C. For applications in an oxygen-free environment, Anton Paar offers an Argon glovebox proofed configuration based on the MCR 703 Space MultiDrive .

Low-temperature options  to match every application are also available. 

Comfortable setup and ease of use

All temperature devices are swiftly and easily integrated and exchanged, and the rheometer reliably adapts to each new setup and temperature requirement. Toolmaster automatically recognizes and configures all connected devices; TruGap controls and adjusts the rheometer’s actual measuring gap; and T-Ready cuts short unnecessary waiting times by immediately detecting temperature equilibration. The integrated non-reflecting interior illumination of the CTD 600 MDR temperature device ensures a perfect view of the sample during measurement. 

Full safety even at high temperatures

All the outside surfaces of Anton Paar’s convection temperature devices for the MCR series are touch-proof up to the highest temperatures. The exhausts are designed with cooling mechanisms to ensure safe and convenient use at any time, at any temperature. During closing of the ovens, an integrated mechanism prevents the shells from touching the measuring system – avoiding damage to the device. 

Real-time insights into samples during measurement

The combination of the integrated interior illumination with the high-quality optical system of the digital eye camera ensures sharp and uniformly illuminated real-time pictures and videos of samples over the complete temperature range. This allows for detailed investigations of different measurement effects, such as edge fracture, sagging, optically visible phase transitions, degradation, and gap emptying. Further, this data can add valuable information to analysis and validate measurement results. The real-time camera pictures and videos are displayed in the media explorer of the rheometer’s RheoCompass software and can be directly added to a diagram and assigned to the measuring points at which they were recorded. The digital eye camera can be installed on CTD in less than one minute.
