The York Scheibel's Column falls in the class of gravity-operated extractors with mechanical agitation. The presence of alternatively agitating and calming sections in a York Scheibel's column yield higher extraction efficiency than the conventional packed column. In the setup acontinuous counter current contact between the solvent and solute phases is made which results into extract and raffinate streams. Rotameters are used to measure the flow of solvent and solute respectively. The continuous and dispersed phase streams are metered and derivedfrom separate containers. Each stage consists of a woven wire mesh section and a mixing section. The propeller speed can be controlled to the desired value by a controller. Total set-up is housed in a well-designed rigid structure. The structure also supports tanks, piping, Rotameter, panel and other units.

•Arrangement is done for changing height of interface zone.

•Control panel comprising of: Standard make on/off switch, Mains Indicator etc.

•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.

•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.

Experimentation/Learning Objectives

•To determine overall mass transfer co-efficient based on continuous & dispersed phase.

•To determine individual `Height of Transfer Unit' based on continuous & dispersed phase.

•To determine overall `Height of Transfer Unit' based on continuous & dispersed phase.
