Density bottles, also known as a pycnometer or specific gravity bottles are mainly used to determine the density of liquids of moderate viscosity. They are not volumetric instruments, however, they are calibrated 'to contain' as in the case of volumetric flasks. Handling. Determine the weight of the dry and empty density bottle.Unless or otherwise specified specific gravity values reported shall be based on water at 27 0 C. So the specific gravity at 27 0 C = K ´ Sp. gravity at T x 0 C. The specific gravity of the soil particles lie with in the range of 2.65 to 2.85. . It was found that the specific gravity value obtained from the partially vacuum and shaking methods provide a reliable value of specific gravity as compare to pycnometer/density bottle method.

Specific gravity, also referred to as relative density, is used to relate the weight or density of liquids to that of water. Specific gravity is a unitless measurement that is derived as a ratio of either the weight of another liquid or the density of another liquid divided by the weight or density of water.
4.2 Of the two test methods described, the pycnometer method (Test Method B, 1.1.2) is the most accurate and precise.For this reason it is the preferred method in case of disputes. The hydrometer method (Test Method A, 1.1.1) is the least accurate and precise, but it is also the simplest and fastest to perform and is often entirely satisfactory for many purposes.A United States Navy Aviation boatswain's mate tests the specific gravity of JP-5 fuel. Relative density, also called specific gravity, [1] [2] is a dimensionless quantity defined as the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.
