Discovery Core Rheometer
Empower Every User to Perform Rheological Measurements
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.
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.
Discover Insights Beyond Viscosity
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.
Rheometer Advantages:
- Precision and accuracy
- Range of measurement
- Controlled shear rate
- Replicate process conditions
- Small sample volume
- Rapid temperature control
Test Modes:
- Flow
- Oscillation
- Transient
Designed to Streamline Every Step
- Automatic gap control provides faster workflow and precise gap positioning. The axial motor automatically raises and lowers the head throughout the method and controls the test gap position with 0.1 um resolution for accurate and reproducible results.
- Touchscreen capabilities go beyond basic controls, providing a new user experience ideal for high-throughput labs. Perform routine measurements directly at the instrument without need for PC interaction.
- Integrated lighting enhances visibility for easier, more reproducible sample preparation leading to increased data accuracy and precision. The sample is automatically spotlighted during user interaction, guiding the operator and signaling test status.
- Smart Swap™ 2 reader automatically identifies attached geometry, recalls dimensions and stored calibrations, and validates geometry aligns with the selected RheoGuide™ method. Smart Swap eliminates common sources of error and enables more efficient operation.
- Compact design incorporates electronics, Peltier and air-cooling heat exchanger in one unit. Compared to modular systems with liquid circulators, the Core Rheometer requires up to 75% less bench space.
Empower your Lab with RheoGuide™ Software
RheoGuide is your entry point to the world of rheology, directly from the Core Rheometer touchscreen. Select a method from the app-style interface and follow instructions and illustrations through every step, eliminating sources of operator error. Results are immediately available on the touchscreen, allowing users to take immediate action, perfect for fast-paced environments.
Rheology testing improves quality and consistency by identifying variations not detected by viscometers, preventing future problems and downstream costs. These insights used in R&D are now available to QA/QC labs, with the ease of use of a viscometer.
Methods are customizable to incorporate every step of your standard operating procedure and instantly indicate Pass or Fail based on your specifications. Test methods are easily synchronized across labs worldwide with consistent operation and data you can trust to drive decisions and solutions.
RheoGuide™ Features & Benefits
- 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.

Core Temperature Technology
Temperature control is key for accurate rheology data to ensure data reproducibility and evaluate materials’ behavior under real-world conditions. The Core Rheometer’s integrated Peltier system provides precise, rapid temperature control. Equilibration time is reduced by up to 60% compared to typical viscometer configurations, minimizing down time between different measurements. Built-in air cooling eliminates the need for a liquid circulator, reducing cost, simplifying operation, and saving valuable bench space.

| Peltier Plate | -10 °C to 200 °C |
| Peltier Concentric Cylinder | 0 °C to 150 °C |
Peltier Plate Geometries
Parallel plate geometries offer versatility for wide ranging materials such as liquids, dispersions, creams and emulsions, gels and pastes, available in sandblasted or crosshatched surface finishes to prevent slip. Cone geometries provide a uniform shear rate, ideal for unfilled liquids. Both plate and cone geometries provide the convenience of small sample volumes (<2 mL) and easy cleaning.
Concentric Cylinder Geometries
Configure your Core Rheometer with concentric cylinders for enhanced sensitivity to characterize viscosities as low as 1 cP, and easy fool-proof sample loading perfect for high-throughput labs.
A variety of upper rotors and lower cups are available to accommodate materials and testing needs, including disposable cups for high-throughput testing.
