Batch Evaporation–Crystallisation Unit

Crystallisation enables the separation, from a solution, of one or more solid compounds dissolved in that solution. During separation, the dissolved compounds transition to the solid state when the required operating conditions (temperature, concentration) are met. The crystals formed are then separated from the liquid phase by filtration. Learn about Batch Evaporation–Crystallisation Unit for educational labs for optimal educational outcomes..
