The TA Instruments | Waters Discovery™ Core Rheometer is an advanced, walk-up–friendly rheological analysis platform designed to empower every user—regardless of skill level—to perform high-quality viscosity and viscoelastic measurements. Built with guided workflows, automated validation, and powerful integrated temperature control, the Core Rheometer brings research-grade rheology capability into quality control, formulation, and production environments.
Engineered for accuracy, usability, and productivity, this instrument enables laboratories to characterize complex materials far beyond single-point viscosity, delivering deeper insights into flow, deformation, and viscoelastic behavior under real-world conditions. It is ideal for testing suspensions, emulsions, gels, creams, slurries, pastes, polymers, inks, coatings, food ingredients, pharmaceutical formulations, and specialty chemicals.
Key Advantages
1. Comprehensive Rheological Insight
Unlike traditional viscometers that only measure a single viscosity value, the Core Rheometer captures the entire viscosity profile across controlled shear rates and oscillatory modes. This allows users to fully characterize the non-Newtonian behavior of complex fluids.
2. True Walk-Up Usability
The instrument’s intuitive touchscreen interface and new RheoGuide™ software enable fully guided operation—with instructions, validation prompts, and illustrated steps—ensuring highly reproducible measurements even from non-expert users.
3. Automatic Precision & Reliability
- Automatic gap control with 0.1 μm resolution ensures precise geometry positioning.
- Smart Swap™ 2 technology automatically detects and validates the installed geometry.
- Integrated lighting enhances visibility and accuracy during sample loading.
4. Compact, Integrated Temperature Control
The Core Rheometer features a built-in Peltier temperature system that provides fast equilibration and accurate control without external circulators, saving bench space while reducing operational complexity.
5. Designed for High Throughput
- Rapid test turnaround
- Pass/Fail evaluation directly on the touchscreen
- Disposable concentric-cylinder options for QA/QC environments
RheoGuide™ Touchscreen Software
RheoGuide provides:
- Step-by-step guided workflows
- Pre-defined and customizable rheology methods
- Automated validation at every stage
- Real-time graphical test results
- Immediate Pass/Fail verdicts for QC environments
- Operator safety alerts during high-temperature steps
- Seamless transfer of methods between instruments and sites
This makes rheology accessible to all users while ensuring consistent, error-free operation.
Measurement Modes
Flow (Steady Shear)
Evaluate viscosity behavior across shear rates.
Oscillation
Assess viscoelastic properties—storage modulus, loss modulus, tan δ, structure stability.
Transient Tests
Yield stress, thixotropy, creep, recovery, and structural rebuild behavior.
Core Temperature Technology
Integrated Peltier systems ensure:
- -10 °C to 200 °C (Peltier plate)
- 0 °C to 150 °C (concentric cylinder)
- Up to 60% faster equilibration
- Built-in air cooling—no external water bath required
This makes it ideal for temperature-sensitive workflows or rapid QC cycling.

Peltier Plate Geometries
- Parallel plates (sandblasted or crosshatched)
- Cones for uniform shear rate
- Very small sample volume (<2 mL)
- Easy to clean, ideal for creams, gels, dispersions, and emulsions
Concentric Cylinder Geometries
- Enhanced sensitivity for low-viscosity samples (as low as 1 cP)
- Consistent, controlled loading
- Disposable cups for high-throughput QC
