Description

The GPC E11 bench is used to study a liquid-liquid extraction system with stirrers.

A gear pump feeds the mixture from the top of the column. A second gear pump feeds the solvent from the bottom of the column. The mixture and the solvent will therefore circulate against the current, which will allow the solvent to extract the solute by shearing the discs on the liquid.

The students will have to start the installation after preparing the solutions and then carry out measurements to verify the effectiveness of the separation.

The rugged design of this equipment makes it perfectly suited for use in a school setting.

Its anodized aluminum structure on multidirectional wheels with brakes gives it a very high robustness as well as great flexibility of integration into your premises. The manufacture of this equipment complies with the European Machine Directive.

The bench is installed on an aluminium profile structure equipped with four braked-directional castors.

The bench has a main power supply box that complies with European electrical standards with standby power disconnector, white voltage presence light, emergency stop button, ground connection and differential protection. It is equipped with a 7-inch touch screen displaying temperature measurements.
The elements in contact with the reagents are made of Teflon, HDPE, stainless steel and borosilicate glass.
