The MCR 702e Multidrive for Dynamic Mechanical Analysis

The Dynamic Mechanical Analyzer MCR 702e MultiDrive is a multifaceted and powerful platform appropriate for the dynamic mechanical analysis of soft, solid and liquid samples.

The unique concept allows dynamic mechanical analysis in tension, bending, torsion and compression, standard and highly complex rheological measurements and also thermomechanical analysis (TMA) with a single instrument.

The system’s modularity permits the integration of a broad range of temperature devices and application-specific accessories and measuring systems to account for all requirements of the greatest variety of different applications.

  • The world’s most multifaceted platform for dynamic mechanical analysis and rheological examinations
  • Precise temperature control from −160 °C up to 600 °C and above
  • Air-bearing-supported moving-magnet drive for force measurements from 0.5 mN – 40 N to analyze stiff and soft materials

Key Features

Two Drive Units for All of the Users’ Applications

The combined air-bearing-supported upper rotational drive and an air-bearing-supported lower linear drive allow linear dynamic mechanical analysis with the linear drive. The torsional dynamic mechanical analysis is carried out using the rotational drive.

A single instrument carries out DMA in torsion, tension, compression and bending, and all types of rheological examinations and even experiments in thermomechanical analysis.

The preference of measuring mode depends on the application. As the system employs sophisticated optical encoder technology, moving-magnet motor and the acclaimed EC motor technology from MCR rheometers, the concept promises highly accurate measurements in DMA and rheology.

Control the Greatest Influence of All — Temperature

The optimization of convection temperature devices generates a homogeneous temperature distribution needed for precise control of the sample temperature. Furthermore, it is possible to employ low-temperature options based on customized liquid nitrogen (−160 °C) or gas chiller option (−90 °C) for accurately controlled cooling.

Moreover, in combination with temperature, a controlled relative humidity can be applied to the sample.

Every measuring system incorporates an integrated temperature sensor with a fixed position in proximity to the clamped sample, such that the measured temperature directly relates to the actual sample temperature. Without the manual positioning of the sensor, the highest reproducibility over the entire temperature range is assured.

The system provides the high-precision temperature control required for highly accurate results for all types of tests.

Benefit from More than 200 Accessories for Rheology

Along with the classic dynamic mechanical analysis, rheological measurements uncover the likelihood of determining the flow behavior of liquids and the deformation behavior of solids. To measure various types of samples, users need various measuring systems, temperature devices and accessories.

By removing the linear motor unit, MCR 702e MultiDrive can be equipped with any temperature device, measuring geometry and/or application-specific accessory recognized from the Anton Paar MCR series to perform standard and complex rheological analyses of the sample.

Special Accessories and Customized Solutions

Special applications require customized and innovative solutions. Anton Paar’s in-house development and production team offer special applications for devices and accessories. The MCR 702e Space MultiDrive, for instance, provides extended available working space and this enables working with complementary measuring instruments and accessories.

Furthermore, users can avail accessories for determining solids that have to be characterized at temperatures of up to 1000 °C or which are immersed in a liquid. Systems are also available for the DMA of solid circular bars in torsion and tension as are shafts appropriate to be combined with any disposable or customized geometry.

Anton Paar provides material pockets along with the typical DMA measuring systems in bending mode for testing powdery samples. Users can contact the company to elaborate on the requirements and identify a customized solution for the measurement task.

Enjoy the Convenient Setup and Ease of Use

The MCR 702e MultiDrive accurately adapts to every new setup. All temperature devices and measuring geometries are easily and swiftly exchanged and integrated. The QuickConnect function permits single-handed connection of the measuring systems and assures quick, convenient system changes without using a screwing mechanism.

Moreover, the use of integrated temperature sensors and completely automated procedures for an optimum alignment (ZeroGap and ZeroAngle) assures accurate measurements without the need for any manual adjustments of temperature sensors or measuring systems.

The patented Toolmaster™ feature automatically identifies and configures all connected devices and measuring geometries.

One Software for All Demands — Multifunctional and User-Friendly

The intuitive RheoCompass™ software helps identify the customized or predefined test templates needed, customize tests and analysis definitions, export the data and create reports. The software provides a wide variety of predefined but individually adaptable analysis techniques, for instance, characterization of time-temperature superposition or glass transition temperature.

As the system employs a Microsoft SQL 2012 database, retrieving and managing data is just as simple as creating it. Filtering the data, for example, by batch number, year or operator, and displaying the data within seconds.
