| Gradient Tube Density |
A method for measuring densities of very small samples, often used in the plastics industry, A vertical glass tube (the gradient tube) is filled with a heterogeneous mixture of two or more liquids, the density of the mixture varying linearly or in other known fashion with the height. A drop or small particle of the specimen is introduced in the tube and falls to a position of equilibrium which indicates its density by comparison with positions of known standard samples. |
