specific gravity bottle

A specific gravity bottle is a laboratory tool used to determine the density or specific gravity of a liquid. It consists of a small, narrow-necked glass bottle with a stopper and a capillary tube attached. To use the specific gravity bottle, the bottle is first weighed empty, then filled with the liquid whose density is to be measured. The stopper is then inserted and any excess liquid is removed with the capillary tube, and the bottle is weighed again. The difference in weight between the empty and filled bottle allows for the calculation of the density or specific gravity of the liquid. This tool is commonly used in various scientific fields such as chemistry, geology, and fluid mechanics to accurately measure the density of different liquids.
