No two liquids have exactly the same boiling point. As such, using a kjeldahl bulb, it is possible to separate any mixture of two liquids by raising the temperature of the mixture to a point where one of the two will boil while the other remains liquid. This classroom or lab quality student distilling apparatus includes a comprehensive instruction manual that discusses how this process is applied in various industries, such as the oil industry. The set also includes two stoppers fitted for the bulb apertures.
