Rheometers / Dynamic Mechanical Analyser (DMA)

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 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.

Core Rheometer is the first system to combine wide-ranging measurements of viscosity and viscoelasticity with streamlined, walk-up usability. The new RheoGuide user interface enables complete operation directly from the touch screen, with direction, illustration, and validation at every step.

The new TA Instruments | Waters  Discovery™ Core Rheometer empowers every user to perform rheological measurements, guiding formulation development, optimizing performance, and ensuring product quality. Whether you are new to rheology, upgrading your quality control testing, or expanding capabilities to meet growing demands, the Core Rheometer empowers your lab to discover insights into your materials’ behavior needed to advance your goals.

While viscometers report only a single viscosity value within a limited range, the Core Rheometer captures the complete viscosity profile, representing material behavior across all relevant conditions. Complex fluids like suspensions, emulsions, gels, pastes, and slurries are non-Newtonian. Their viscosity changes with the applied shear rate and time; it is not a single value. Characterizing the full range of viscosity is critical to understanding flow behavior under real-world conditions.

Rheometer Advantages:

• Precision and accuracy
• Range of measurement
• Controlled shear rate
