BeScan Lab – Determination of Dispersion Stability

The BeScan Lab is a latest-generation measuring device for determining the stability of dispersions using static multiple light scattering (SMLS). Suspensions, emulsions or foams can be analyzed in their original state (up to 95% by volume) and at temperatures up to 80 °C. The BeScan Lab is ideal for optimizing the formulation of a system with regard to storage stability, for quality control of various dispersions and also for quantitative analysis of different destabilization phenomena.

By measuring the scattered light intensity in transmission and backscattering, it is possible to analyze diluted and highly concentrated systems. Various phenomena such as sedimentation, creaming, flocculation, coalescence or phase separation can be identified. For this purpose, the sample is analyzed several times over the entire height in order to detect changes in transmission/backscattering as a function of height and time. With a resolution of 20 µm, destabilization processes can be detected much faster than with the naked eye. In addition, analyses at up to 80 °C can accelerate destabilization effects and measurements can be carried out as a function of a temperature ramp.
