Optimizing Product Stability with Advanced Interfacial Rheology

Emulsions and foams are dynamic systems, continuously in motion during transportation and production. The DSA30R Drop Shape Analyzer excels in capturing this dynamism by examining how the interfacial or surface tension of droplets or bubbles reacts when stretched. The capability to measure the speed and degree of this reaction is crucial, as it significantly impacts the stability of food and personal care products, as well as the efficiency of enhanced oil recovery (EOR) processes.

By providing detailed interfacial rheology measurements, the DSA30R represents an essential tool for optimizing the formulation and process parameters of various products. Its applications range widely, from food and personal care emulsions and foams to surfactant flooding mixtures used in EOR.

Furthermore, the DSA30R supports a variety of measurement methods, including the analysis of interfacial rheological behavior and surface or interfacial tension, making it versatile for research and development across several domains such as defoamers, demulsifiers, surfactant development, and more.

Technological Sophistication for Accurate Measurements

The DSA30R employs advanced technology allowing precise oscillation of drops or gas bubbles for elasticity and viscosity analysis across a wide dynamic range. Its high-precision piezo drive facilitates the generation of exact sine waves, covering a broad spectrum of frequencies. This feature is especially beneficial for samples containing surfactants, providing insights into their temporal and mechanical stability.

With its intuitive ADVANCE software, the DSA30R simplifies complex interfacial rheological analytics, offering easy sample changing, automatic dosing feed coupling, and bubble-free filling. The instrument assures quick, easy, and repeatable measurements. Moreover, it operates effectively in controlled thermal conditions, further enhancing its reliability and application reach.
