Abstract
Compositions include an aqueous solution of an organic dye of molecular weight in the range of about 300 to about 1,000 and a density-enhancing material. An amount of the density-enhancing material in the aqueous solution is sufficient to achieve a density of about 1.0 to about 1.3 g/mL. The composition has a viscosity of about 3.5 to about 5.0 centipoise. The compositions are useful in assessing the adequacy of a liquid handling mixing device to mix a reaction mixture.
