A pendant drop surface film balance implemented with a multi-subphase exchange, nicknamed the OCTOPUS, allows for mimicking digestive conditions by the sequential subphase exchange of the original bulk solution with simulated gastrointestinal fluids. The simulated in vitro digestion is monitored by recording in situ the interfacial tension of the digested interfacial layer.
