A novel device for sampling an unstable liquid-in-liquid or gas-in-liquid dispersed system has been developed. Samples of a dispersed system can be easily collected from any location in an operating stirred tank reactor. A sampled specimen is fixed instantaneously, enabling easy observation under a microscope and direct measurement of dispersion characteristics, such as size and/or distribution of the dispersed phase and hold-up through the use of an image analyser. The specimen can be stored
more » ... r a sufficiently long time, with the dispersion maintained completely stable until measurement.
