TA Instruments’ Discovery Hybrid Rheometer is the world’s most versatile platform for rheological measurements. Advances in core measurement technology enable more sensitive measurements with superior precision. This empowers you to measure lower viscosities and weaker liquid and soft-solid structure, while consuming less material. Superior dynamic performance gives a higher level of accuracy in measurements of G’ and G” so you can make decisions quickly, with confidence.

Thoughtful hardware and software design results in a complete system that simplifies every user interaction. Routine functions are faster and more intuitive, so you can accomplish more with less training.

The performance of the Discovery Hybrid Rheometer is supported by the widest range of powerful, easy-to-use environmental systems and accessories that allow you to replicate demanding environmental conditions, incorporate complementary simultaneous measurements, or extend your rheometer beyond conventional shear rheology.

The ARES-G2 is the most advanced rotational rheometer for research and material development. Both platforms have a full range of environmental systems and measurement accessories, powered by SmartSwap™ technology for fast exchange and automatic configuration.

Available models

The HR 10 builds on the field-proven accuracy and reliability of the Discovery Hybrid Rheometer family. Incorporating advanced technologies found on the HR 20 and HR 30 models, the HR 10 delivers industry-leading performance at a cost-effective price point that is suitable for a wide range of general viscosity and viscoelasticity measurements and for use in round-the-clock production control.

The HR 20 is an exceptional multi-purpose rheometer that can handle everything from cutting-edge research and development laboratories to continuous deployment in production control environments. With optional linear Dynamic Mechanical Analysis and the widest range of easy-to-use accessories, the HR 20 is ready to handle any set of challenges, from complementing shear rheology to testing solids under tension, compression or bending.

The HR 30 is a premier research-grade rheometer for scientists looking to advance the boundaries of material science by exploiting its unparalleled measurement sensitivity and accuracy. With integrated linear Dynamic Mechanical Analysis, the HR 30’s two-in-one instrument capabilities empowers users to explore entirely new possibilities for mechanical testing.

ARES-G2

The ARES-G2 is a premier high-performance rheometer that provides the most accurate rheological data over a wide range of conditions. The ARES-G2 is routinely used in leading R&D labs and manufacturing sites to relate the material chemistry to its processability and end-use properties for a wide variety of materials ranging from proteins to polymers, coatings to composites, and everything in between.

Unlike competitive systems, the ARES-G2 is the only rheometer equipped with the industry-leading separate motor and transducer technology (SMT) which eliminates any inertial contributions and provides users with unrivaled data accuracy over a wide range of test conditions. Coupled with fast-responding, uniform, accurate temperature control, the ARES-G2 allows users to perform rheological measurements while replicating processing and end-use conditions. These measurements thus enable users to optimize the processability of new and existing materials in a time- and cost-effective manner, define robust CQAs and ensure that the finished products meet the end-use KPIs around product performance, consumer perception and storage stability.
