The vacuum drying oven is a piece of laboratory equipment designed for heating and drying materials under negative pressure. Its primary advantage lies in lowering the boiling point of liquids, which enables the efficient drying of heat-sensitive, easily oxidized, or complex-composition samples at lower temperatures.

How should the heating temperature be controlled in a vacuum drying oven?

Various models of electric vacuum drying ovens are designed and manufactured to meet the common requirements of different users. Although they may differ in terms of control methods, construction, materials, and design, the underlying heating principles or techniques remain essentially the same. Therefore, when using the equipment for the first time, it is advisable to conduct a trial run: record the surface condition of the items to be heated, the quantity of items, their placement, and the readings from the instrument and thermometer. Once the drying process is complete, evaluate the results to determine the optimal quantity of items and the appropriate instrument (or thermometer) readings for future use.
