A gravity-driven dram brings the solvent containing the extracted compound back to A, thereby allowing closed loop operations long enough to achieve the desired extraction. The Multifunctional Extraction Plant system is made up by a reservoir A where the extracting solvent is loaded; the solvent is then vaporized by means of an electrical heater. The system is manufactured in borosilicate glass which allows it to be used with any kind of solvent. It is assembled on anticorrosion metal structure. The vapors in column B undergo partial rectification; the pure solvent vapors are subsequently condensed in C and the liquid eventually reaches the extractor D which contains the phase from which the compound has to be extracted.

Freeze Drying is the process by which the solvent of a solution is turned from solid state into gaseous state without going through the liquid state, that is to say that the solvent of a solution (generally water) is separated by sublimation. The Freeze Drying Plant allows to perform the entire freeze drying cycle, thus enabling the student to fully understand both the process and the problems involved in plant design. It is used to preserve foods such as fruit juices, vegetables, meat, and fish.
The Freeze Drying process consists of two stages:
First, the product to be dried is frozen below its freezing point.
Second the solvent, now in the solid state, is sublimated by heating under vacuum. Evaporated water is frozen on a very cold surface and then eliminated.

Cathodic protection techniques are commonly used to protect steel pipelines, structures and storage tanks, ships, oil platforms and structural elements of oil wells. Cathodic protection is a technique used to control the corrosion of a metal surface by making it work as a cathode, coupling it with a less noble metal (sacrificial anode) or with a cathodic power supply. The experiments can be carried out at different temperature and oxygen concentration, using different kinds of reference electrodes and sacrificial anodes as well as various metal samples with or without surface treatment. This trainer enables the study of the cathodic protection with sacrificial anode or impressed current (at constant potential and at constant current). The trainer can be connected to a PC (not supplied) running Windows and a dedicated software for the experiments data acquisition and storage.
