Discovery Core Rheometer

last updated：Jul 10, 2025

With DCR, it is possible to analyze the tactile sensations that cannot be measured with a conventional viscometer.

The DCR (Discovery Core Rheometer) provides precision and detailed analysis that surpasses traditional viscometers in evaluating the viscosity and viscoelasticity of hand creams and shampoos. The feel and performance of hand creams and shampoos heavily depend on their viscosity and viscoelastic properties. Conventional viscometers can only measure viscosity at a single shear rate, but the DCR analyzes viscosity and viscoelastic properties across a wide range of shear rates, allowing for the assessment of product feel and stability. This enables optimization in product development and quality control. Key Features: - High-precision measurement: Accurately measures fine viscoelastic properties that cannot be detected by viscometers. - Wide shear rate range: Adapts to various usage conditions and analyzes detailed viscoelastic properties. - Real-time analysis: Evaluates viscosity and viscoelastic properties in real-time during the manufacturing process. - User-friendly: Intuitive operation and advanced data analysis functions make it easy for anyone to use. By using the DCR, you can fully understand the viscosity and viscoelastic properties of hand creams and shampoos, enhancing product feel and quality. The DCR provides detailed data that cannot be obtained from traditional viscometers, making it the optimal solution for the development and quality control of personal care products.

Detailed information

Figure 1: A schematic diagram showing the range of shear rates at which the process occurs. All of these can be modeled using a rheometer. A narrow range of shear rates accessible with a viscometer is indicated.
Figure 2: Virtual data of a face cream showing how viscosity is affected by shear rate. The rheometer should be able to identify all the displayed actions, while the viscometer will only show the highlighted central portion.
We investigated the reasons why one formulation of a liquid emulsion adhesive designed for high-speed coating, using a TA Instruments rheometer, significantly underperformed compared to competitors. This performance deficiency led to the occurrence of voids on metal substrates and an increase in cases of adhesive failure (Figure 3a). Figure 3: (a) A schematic showing the differences in operation between Formulation 1 and the competing product.
The viscometer was able to show the differences in viscosity between samples, but there was no high shear rate data or low shear rate data. 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.
