Spinning Drop Tensiometer

Measurement of interfacial tension in a wide range for optimizing emulsions

The SDT Spinning Drop Tensiometer measures interfacial tension with a high degree of accuracy and a particularly wide range down to very low values. The SDT is the ideal solution for the quality control and development of emulsions and surfactants thanks to its enormous bandwidth, small sample volumes, and simple handling during preparation. The instrument is particularly well-suited for analyzing the interfacial behavior of mini- and microemulsions, e.g. for enhanced oil recovery (EOR) or the pharmaceutical and cosmetics branches.

Specifications:

• Measurement of interfacial tension in an extremely wide range starting from 10-6 mN/m

• Analysis using the Vonnegut drop diameter method

• Analysis using the Young-Laplace drop shape curvature method

• Long-term measurements for investigating surfactant dynamics

• Temperature-dependent analyses
