Condenser, a metering pump and a liquid-ring vacuum operation. The apparatus includes two glass tank for collection of evaporated solvent and concentrated product. The evaporator is used for separation of oxygen from air flow by absorption in counter flow with a water film. A compressor is used to supply ambient air to the trainer while 2 pumps are used for circulation of solvent through absorption & desorption column. 2 hand-held measuring units for measuring the oxygen concentration upstream and downstream of the absorption column.

Detailed Operation & Maintenance Manual is provided along with the trainer.
