The two high-end models of the new MCR Evolution series, MCR 702e MultiDrive and MCR 702e Space MultiDrive, are the most versatile rheometers available. Alongside all standard rheological test modes they can be equipped with an additional lower drive unit. This means that you can perform rheological tests with two torque transducers and drive units at once – opening up multiple possibilities for your research. There are no limitations regarding the used test modes, measuring systems, accessories, and temperature devices, and no limitations on measurement precision. Additionally, MCR 702e Space MultiDrive provides the maximum working space and thus makes it easy to work with accessories and additional instruments. In short, this is the system of choice to cover all possible rheological applications both now and in the future.

One rheometer, all rheological working modes
The combination of two air-bearing-supported rotational drive units enables you to perform rheological measurements in Combined Motor Transducer (CMT) mode and in Separate Motor Transducer (SMT) mode. Using a single air-bearing-supported EC motor unit in the CMT mode, you can make the most of the motor’s TruStrain™ capability and perform ‘classic’ stress-controlled tests. In the SMT mode one motor is operated solely as a torque transducer, while the other motor is used as a drive unit only, to get the purest rheological results even in the transient regime of the measurement (e.g. stress relaxation, start-up shear) and over a broad range of amplitude and frequency in oscillatory measurements. With all their working modes MCR 702e MultiDrive and MCR 702e Space MultiDrive complete the successful MCR series and contribute to making the MCR rheometers the most cited instruments in scientific rheological investigations.

Push back the limits of material characterization with counter-movement mode
In the counter-movement mode, the reometer employs both air-bearing-supported EC motors as drive units as well as torque transducers. Both motors are easily set to move in opposite directions, which can be used e.g. to create a fixed stagnation plane in a sample for advanced structure analysis of materials under shear using the microscope. This mode is also used with a universal extensional fixture for extensional tests down to minimal measured torques. Regarding speed, the counter-movement mode simply ‘doubles the score’ – up to a maximum speed difference of 6000 rpm which broadens the shear rate range for high shear applications.

Ready for DMA in torsion, tension, bending, compression, and more
Instead of a lower rotational drive, an additional lower linear drive can be used to perform DMA in bending or compression mode using measuring systems such as three-point-bending, cantilever, or parallel plate. Furthermore, in combination with geometries for films, fibers, and rectangular samples the linear drive can be used to perform DMA in tension whereas the upper rotational drive is used for DMA in torsion – both within a single test definition. Additionally, the linear drive is capable of performing thermomechanical analysis, creep and recovery or relaxation tests.

The best now better: The device for applications that were previously unthinkable
The new MCR 702e Space MultiDrive is designed to provide a unique maximized workspace below the rheometer support plate and on both sides of the instrument. This allows not only the easy installation of accessories but also the easy combination with additional external setups suitable for advanced material characterization. For example, MCR 702e Space MultiDrive allows you to combine confocal microscopy and rheology. In addition, the rheometer's separate electronics box makes it now possible to set up the rheometer where space is limited or in a laboratory glovebox, even when using inert gas (nitrogen, argon) atmosphere e.g. for high-temperature measurements on samples with a certain hazard level.

Measure and control the temperature where it matters
Control the greatest influence of all – temperature – by using high-precision temperature control units in combination with Anton Paar’s innovative optoelectronic technology. The technology enables contact-free data transmission based on light emission and the photovoltaic effect to detect the true sample temperature. This enables temperature determination without affecting torque sensitivity in Separate Motor Transducer (SMT) mode and also in counter-movement mode. The sensor is positioned directly in the measuring system very close to the sample (only 1 mm distance) which reduces possible offsets between the sample temperature and the temperature measured at the sensor. This enables the accurate determination of the sample temperature even during step or ramp-like temperature changes.

More than 200 accessories and smart features to fit all of your applications
MCR 702e MultiDrive and MCR 702e Space MultiDrive are ready to be equipped with any measuring system, temperature device, and/or application-specific accessory known from the Anton Paar MCR series in order to carry out standard and sophisticated rheological analyses of your sample. The patented Toolmaster™ feature automatically recognizes and configures all connected devices and measuring systems. Additionally, the QuickConnect function allows one-hand connection of the measuring systems. Both features ensure the highest flexibility and minimum work needed to adapt the configuration to your needs.
