MCR 703 MultiDrive and MCR 703 Space MultiDrive are the most adaptable advanced rheometers available on the market. In addition to the standard features of the MCR 503, these rheometers can be equipped with an optional lower drive unit.
This allows users to perform rheological tests with two torque transducers and drive units simultaneously, expanding research possibilities.
There are no restrictions on test modes, measuring systems, accessories, temperature devices, or measurement precision. MCR 703 Space MultiDrive offers maximum working space, allowing for the use of accessories and additional instruments.

Key Features
One Rheometer, All Rheological Working Modes

This rheometer is best-suited for applications requiring high measurement precision. A combination of two drive units allows users to take rheological measurements in both Combined Motor Transducer (CMT) and Separate Motor Transducer (SMT) modes. Using a single air-bearing-supported EC motor in CMT mode, users can leverage the motor's real-time position control (TruStrain) and conduct 'traditional' stress-controlled testing.
To achieve the best results, in SMT mode, one motor is used solely as a torque transducer, while the other serves as the driving unit. This makes the advanced rheometer suitable for transient regimes such as stress relaxation, start-up shear measurements, and oscillatory testing across a broad frequency range.

In counter-movement mode, the advanced rheometer uses both air-bearing-supported EC motors as drive units and torque transducers that move in opposing directions. Create, for example, a fixed stagnation plane in a sample while observing with a microscope to conduct advanced structural analysis during measurements.
When combined with the universal extensional fixture, this mode allows for extensional testing down to minimal measurable torques and up to unattainable elongations with Hencky strains greater than eight.
With these characteristics, this sophisticated rheometer provides a more thorough understanding of strain hardening. The counter-movement mode simply doubles the speed score, with a maximum speed differential of 6,000 rpm.
DMA in Torsion, Tension, Bending, Compression, and More

MCR 703 is more than a rotating rheometer; it is a multifunctional advanced rheometer that can also do dynamic mechanical analysis (DMA). It conducts DMA in bending or compression by substituting the lower rotating drive with a linear drive and employing geometries such as three-point-bending, cantilever, or parallel plates.
Furthermore, when combined with geometries for films, fibers, and rectangular and cylindrical samples, the linear drive can execute DMA in tension, whilst the top rotating drive is employed for DMA in torsion. This also enables axial-torsional DMA on a single specimen within a single test specification, as well as the measurement of Poisson's ratio and the rapid, direction-dependent characterization of anisotropic materials.
Previously Unthinkable Applications

MCR 703 Space MultiDrive enhances the remarkable performance of the flagship rheometer, MCR 703 MultiDrive. It is designed to provide unparalleled modularity, flexibility, independence, and functionality for all types of rheology and combination approaches.
The open instrument design increases working space, allowing users to connect the MCR 703 Space MultiDrive to multiple additional external setups for enhanced material characterization (e.g., confocal microscopy and rheology simultaneously). Furthermore, the rheometer's separate electronics box now allows it to be set up in tight spaces or in a laboratory glovebox, even when employing an inert gas (nitrogen, argon) environment (e.g., for high-temperature measurements of materials with a particular hazard level).
More Than 200 Accessories

MCR 703 MultiDrive and MCR 703 Space MultiDrive can be used with any Anton Paar MCR measurement system, temperature instrument, and/or application-specific accessory to perform routine and complex rheological investigations. This enables the testing platform to be utilized not just for rheology and DMA, but also as a powder rheometer, tribometer, and universal tester.
The Toolmaster function detects and configures all linked devices and measurement systems. Furthermore, the QuickConnect feature enables one-handed connection of the measurement systems. Due to this versatility, the sophisticated rheometers are easily adaptable and simple to configure to meet specific requirements.
