Description

The GPC E11 bench allows the study of a liquid-liquid extraction system with rotating discs.

A gear pump provides supply of the mixture through the top of the column. A second gear pump ensures the solvent supply from the bottom of the column. The mixture and the solvent therefore will circulate at counter-current, which will allow the solvent to extract the acetic acid from the water by shearing of the discs on the liquid.

Students will study the liquid-liquid extraction system.
The robust design of this device makes it suitable for use in schools.
The equipment is set up on an Anodized aluminium frame on casters wheels. This gives it great strength and a flexibility of integration into your premises.
The manufacture of this equipment complies with the European standard for machinery manufacturing.
