Description

The GPCE40 bench allows the study of liquid-liquid extraction with rectification.

First, we will perform a liquid-liquid extraction and then the extract is sent to a rectification column (distillation) to recover the solvent and to enrich the extract.

The robust design of this equipment makes it perfectly suited for use in schools.

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