The set-up consists of a glass column packed with Rasching rings. Continuous counter current contacts between the solvent and solute phases are made, which results into extract and raffinate streams. Flow meters (Rotameters) are used to note the flow of solvent &solute respectively. The continuous and dispersed phase streams are metered and derived from separate containers. The total set-up is housed in a well-designed rigid structure. The structure also supports tanks, piping, Rotameters, panel and other units.
