Laboratory furnace heating method used

1, the heating
⑴ direct heating: Suitable for high temperature decomposable in solution or pure liquid, usually placed in containers filled with liquids, asbestos online with a gas lamp (or experimental furnace) heating.
⑵ heated on a water bath: For above 100 ℃ decomposition or combustion of volatile solution or pure liquid.
⑶ heated on the sand bath: General requirements at 100 ~ 400 ℃ heat evenly between those suitably heated sand bath.
2, evaporated
And heating the liquid, like, according to the thermal stability of the liquid, respectively by direct heating, water bath heating and a sand bath heated to evaporate. In order to accelerate the evaporation rate, in addition to an appropriate increase in temperature, the need to expand the evaporation area. Evaporation pan evaporation container used. During evaporation, the evaporation of the liquid remaining in plate should not exceed the total capacity of 2/3.
