Key features
The best now better: the new MCR Evolution series
For more than 25 years we have continuously extended our portfolio in close collaboration with our most important innovation driver, YOU, our highly valued customers and rheometer users. We are now proud to present the new MCR Evolution series: rheometers that push your work one step ahead.

The benefits of the new MCR Evolution series
- The fastest one-hand coupling and decoupling of measuring geometries in just one second – even at extreme temperatures (-160 °C to 1000 °C): Novel quick-connect mechanism
- Precisely measure even low-viscosity samples with our entry-budget model: Higher sensitivity (from 7.5 nNm to 2 nNm)
- Stable results even for long-term measurements with low torque: Improved thermal management within the EC motor starting from MCR 302e
- More space for sample handling and exchange of accessories: Extended working height starting from MCR 302e
- The only device on the market with a trimming mirror for a 360° view of the sample with no blind spots, which avoids sample preparation errors and leads to highly reproducible results.
- Detection of any sample behavior change even at the shortest time scales: Reproducible duration of each measuring point down to 1 ms
- Full pharma compliance: The best pharma package for the RheoCompass software (21 CFR Part 11, full data integrity according to ALCOA+)

Takes work off your hands: Unique motor and sample-adaptive controller technology
The MCR Evo series builds on 25 years of research, development, and constant improvement. This results in technology which pushes the boundaries of rheometry. The combination of the EC motor (Permanent Magnet Synchronous Motor) using a high-precision air bearing with active thermal management, integrated normal force sensor, and a high-resolution optical encoder, for example, allows rheological measurements at the lowest torques ever. The unique sample-adaptive controllers for measurement in rotation (TruRate™) and oscillation (TruStrain™) work for 99 % of all samples and measurements “out of the box” with the perfect combination of speed and accuracy – save time and nerves and even get better data at the same time!

Excellence in every component and every work step
After decades in the field, Anton Paar understands and anticipates what is required for outstanding rheological analysis. With this knowledge in mind, we designed every component and created every handling step to be part of a smooth and intelligent whole:
- The patented Toolmaster™ technology automatically recognizes measuring systems
- One-hand exchange of measuring systems due to the QuickConnect coupling
- T-Ready™ detects sample temperature equilibration in real-time
- The TruGap™ feature detects the real measuring gap
- The trimming mirror gives you a 360° view of the sample and thus supports high measurement repeatability. And many more

Choose from more than 100 test templates, set report filters, and use remote control
The intuitive RheoCompass software offers predefined as well as customized test templates and analysis definitions. Furthermore, it is possible to export your rheological data and generate reports. Data can easily be filtered by e.g. year, batch number, or operator, and displayed within seconds. Due to the Ethernet connection, the rheometer can be remote-controlled from anywhere via the company network. Gap setting, adjustments, and tests can also be started directly from the MCR rheometer, minimizing annoying switches between the computer and the device, e.g. during sample preparation.

Unlimited possibilities: add one of more than 200 accessories
Whatever your rheological applications are and will be in the future – Anton Paar rheometers are quickly and easily adapted to meet your needs. Their flexibility makes them the most cited instruments in scientific publications on rheological investigations. An extensive range of application-specific accessories is available to extend the rheometer’s capabilities, including DMA measurements, extensional rheology, rheo-optics (e.g. microscopy and Raman spectroscopy), magneto- and electrorheology, dielectric spectroscopy, interfacial rheology, UV curing, pressure- and humidity-dependent rheology, tribology, and many more. A wide range of temperature accessories allow you to apply and control temperatures from -160 °C to 1000 °C.
