SDT – 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.
Applications
☑️ Development of emulsions and microemulsions
☑️ Surfactant flooding in enhanced oil recovery (EOR)
☑️ Formulations in pharmaceuticals and cosmetics
☑️ Bioavailability of drugs
☑️ Food emulsions
☑️ Surfactant research
Measuring Methods
☑️ Interfacial tension using the diameter or curvature of a drop of a light phase inside a heavy phase in a rotating capillary
☑️ Carrying out a measurement up to 20 consecutive times and displaying the results together
Measuring Results
☑️ Interfacial tension between two liquids
☑️ Drop image evaluation according to Vonnegut or Young-Laplace
☑️ Time- and temperature-dependent results
