Abstract: A special measuring bottle for measuring volume of solid includes a bottle body and a lid body. The bottle body is filled with a liquid and has an accommodating cavity to be accommodated with a sample solid and a reading cavity communicating with the accommodating cavity. The size of the inner edge of the accommodating cavity is larger than that of the reading cavity. Meanwhile, the accommodating cavity is formed an opening, and the reading cavity is arranged a plurality of graduations available for reading the level position of liquid. The lid body is sealed at the opening just like a shroud. Thereby, when the volume of a solid is measured by the displacing method, the accuracy of measurement by the special measuring bottle is higher than that by a common graduate of close volume, and by the special measuring bottle the specific weight of the sample solid can be less than that of the adapted liquid.
