Immiscible fluids find diverse applications, yet their interfacial tension σ remains a fundamental property that governs their performance. Therefore, accurate and efficient methods to measure interfacial tension facilitate development and refinement of fluid formulations. Microfluidic technology offers a new high-throughput platform for such measurements. In our approach, drops are produced and their dynamics in an extensional flow gradient are analyzed in real-time, and applicability to a broad range of interfacial tension is demonstrated.
