3. a preparation used in treating histologic specimens.
contrast medium a radiopaque substance used in radiography to permit visualization of body structures. Called also contrast agent.

64, 0,97 The fourth column lists the solvent used together with the water as dispersion medium.
Only the mass density of the dispersion medium [rho.
The shape and the location of the minima of all scattering curves could be well fitted by only varying the mass density of dispersion medium.
An emulsifier hinders the coalescence of droplets when it dissolves better in the dispersion medium.
The explanation that w/o emulsions are stable because an electric double layer exists at the interface seems untenable since the dielectric constant of the dispersion medium is low.
Emulsion type is established easily by determining the properties of its dispersion medium: the ability of an emulsion to wet a hydrophobic surface; its potential to be diluted with water; the ability of an emulsion to be colored when dye, which dissolves in the dispersion medium, is introduced and the electric conductivity of an emulsion.
w] in the latter is that the stabilizing layer for the polymerically stabilized latex does not extend as far into the dispersion medium, enabling more particles to be packed into the same volume of water while maintaining a relatively low viscosity.
The polarity of dispersion medium was adjusted by mixing methoxyethanol and ethanol at different ratios.
The dispersion medium prepared with the methoxyethanol/ethanol ratio of 0.
It should be noted that higher latex yields were obtained with the more polar dispersion medium for a constant initiator concentration.
The tendency observed in the more apolar dispersion medium may be explained as follows: In the dispersion polymerization, the formation of primary particles begins with the agglomeration/precipitation of the growing oligomer chains.
As seen here, higher latex yields were usually observed with the higher stabilizer concentrations especially in the more polar dispersion medium (e.
