This type of equipment, has a magnetic stirrer capable of heating the substance automatically, has a magnet device or shaking rod, where the dissolution of the samples is used. In addition, it has a hot plate, with a flat structure, on which the liquids to be shaken and heated are placed; made from heat conductive materials such as aluminum or ceramic. They have also been developed to exclusively heat sources of infrared radiation.
Similarly, the heating and shaking iron, has an element of an electrical resistance, a control system (on, off, temperature control, shaking control and its respective motor). The motors used in this type of instrument are generally of single-phase induction type, referred to as degraded pole type.
