A special instrument is required for constant temperature heating and drying of the sample. The drying oven is a commonly used laboratory drying equipment, which is divided into an electric blast drying oven and vacuum drying oven. Both the water bath and the metal bath are thermostatically controlled, the difference is that the heating media is different and the temperature control range is different. The heating mantle is a heating instrument, which is mostly used for precise temperature control heating of glass containers, and some models have the function of magnetic stirring.
