  • Patent number: 8424369
    Abstract: A surface tension measuring device and a method thereof are revealed. The surface tension measuring device includes a container and a hole. A liquid analyte is filled into the container and the hole is disposed on a wall surface of the container while the liquid analyte forms a drop on the hole. The surface tension of the liquid analyte is correlated with an internal gas pressure inside the container, an external gas pressure outside the container and a level of the liquid analyte. Thus the surface tension of the liquid analyte is obtained by control of the increasing of the liquid analyte level or pressure difference inside and outside the container. Therefore, the reduction of measuring time, less space occupied, lower equipment cost and reduced operation complexity are achieved.
