Hybrid viscometer and rheometer 'DCR'
So that all users can perform rheology measurements.
The Discovery Core Rheometer is the first system to provide extensive measurements of viscosity and viscoelasticity with simple operability. New feature: The RheoGuide user interface allows operation from a touchscreen, providing guidance, visualization, and verification at each step. 【Discover Insights Beyond Viscosity】 Viscometers only report a single viscosity value within a limited range, whereas the Core Rheometer captures a complete viscosity profile, representing the material's behavior under all relevant conditions. Complex fluids such as suspensions, emulsions, gels, pastes, and slurries are non-Newtonian fluids, and their viscosity changes depending on the applied shear rate and time. Characterizing the full range of viscosity is crucial for understanding flow behavior under real-world conditions. 【Key Features】 Advantages of the Rheometer: ■ Accuracy and precision ■ Wide range of measurements ■ Controlled shear rate ■ Reproducibility of process conditions ■ Measurable with small sample sizes ■ Rapid temperature control Test Modes: ■ Flow ■ Oscillation ■ Transient

We investigated the reasons why one formulation of liquid emulsion adhesive designed for high-speed coating, using a TA Instruments rheometer, significantly underperformed compared to competitors. This performance deficiency resulted in the occurrence of voids on metal substrates and an increase in cases of adhesive failure (Figure 3a). Figure 3: (a) Schematic diagram showing the differences in operation between formulation 1 and the competing product.

The viscometer showed the differences in viscosity between samples, but there was no data for either high shear rate or low shear rate. It was only when using the rheometer that it became clear that the zero shear viscosity of the competing product was eight times higher. This was the key. A high zero shear viscosity means that the competing product does not flow after application and stays in place.
