TA Instruments - Discovery Core Rheometer
The 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.
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 understand flow behavior under real-world conditions.

- Walk up usability: Perform routine tests directly from the instrument touchscreen, from start to finish, without need to interact with the PC.
- Guided operation: Pre-defined Methods and on-screen instructions and illustrations direct operator actions in a step-by-step workflow enabling every user to perform successful rheology measurements with minimal training.
- Validation throughout: Common sources of error are eliminated- the correct geometry is installed and calibrated, the sample information is updated, and every step is complete. When operators never miss a step, data is more accurate.
- Ensure operator safety: On-screen messages alert if the method exceeds safe-touch temperature with reminders for proper PPE. RheoGuide prompts operator interactions when needed and disables interaction when the head is in motion.
- Rapid results: Automated analysis results are displayed on the touchscreen immediately upon test completion, along with pass or fail indication. Eliminating the need for routine manual data processing is ideal for fast-paced Quality Assurance/Quality Control testing labs.
- Synchronize methods: Discovery Hybrid Rheometer methods directly transfer to Core Rheometers to replicate R&D’s measurements in QC testing. Methods shared across instruments and sites help ensure every operator performs the same measurement.
- Powered by TRIOS™ software: Customize RheoGuide methods and access all raw data files for additional analysis through TRIOS, the popular software platform from TA Instruments.
