CHARLOTTE COLLOID MILL State of the Art Product ProcessingThe Charlotte Colloid Mill provides many years of clean troublefree operation. Advanced system design and construction furnishes a self cleaning action through normal use. Simply flushing with water or an appropriate solvent is standard procedure, resulting in minimal cleanup time and maintenance costs.
STABILITY OF COLLOIDAL SYSTEMS, AGGREGATION, .STABILITY OF COLLOIDAL SYSTEMS, AGGREGATION, COAGULATION, FLOCCULATION. The separation into two liquid phases in colloidal systems is called coacervation. It occurs also, though rarely, in hydrophobic sols. The phase more concentrated in colloid component is the coacervate, and the other phase is the equilibrium solution .

Colloids University of DenverA colloidal system consists of an internal phase, which is the material of colloidal dimensions, and an external phase, which is the material in which the colloid is dispersed. These designations are analagous to the terms solute and solvent used for simple solutions (which form a single Gibbs phase).
STABILITY OF COLLOIDAL SYSTEMS, AGGREGATION, .STABILITY OF COLLOIDAL SYSTEMS, AGGREGATION, COAGULATION, FLOCCULATION The terms stable and stability are used in rather special and often different senses in colloid science: the relationship between these usages and the formal thermodynamic usage is outlined below.
