Abstract
An automatic cleaning equipment for solvents and volatile chemicals that enables the re-use of substances used in a laboratory. In a distillation vessel (1) there is a combination stirrer, which stirs, measures the temperature and acts as a base valve. In the combination stirrer, there is a tube made of inert material, there is a stirrer motor and a solenoid or motor operating the base valve. Inside the tube, there is a drive magnet rotating on an axle, and a temperature sensor. The actual paddle of the stirrer contains two magnets and is rotated outside the tube by the drive magnet. A filling vessel (2) is equipped with a separate base valve and overflow pipe. A fraction cutter (5) permits taking of a pre-fraction, a main fraction and post-fraction.
