Microwave ovens

For a chemist, drying wet samples and acid decomposition of samples were always a subject of concern. Nowadays microwave ovens are used for this purpose across the world. The main advantage of this system is that the device takes only a few minutes of dissolution time. In an electromagnetic spectrum, micro waves lie in between infrared radiation and radio waves. Electric field is responsible for energy transfer here. When the microwave energy passes through the sample, the molecules of the sample which are equivalent to electric diploes will try to align with the applied electric field. The major parts of microwave oven are magnetron, isolator, waveguide, cavity and mode stirrer. Magnetron generates microwave energy which is sent to cavity through the waveguide. Stirrer distributes the energy and isolator keeps the energy away from the magnetron.
