Similarities: Both vacuum oven and drying oven can be used for articles drying, baking wax, sterilization, they all play an important role in biochemistry, chemical pharmaceutical, medical and health, environmental protection and other research and application fields, is one of the laboratories commonly used experimental equipment.
Difference: A vacuum oven is to use the principle of vacuum pumping to achieve the drying of articles. The air blasting oven uses the air circulation cycle in the oven to drive the hot airflow to achieve drying purposes.
How to choose vacuum drying or blast drying?
The vacuum environment of vacuum heating oven greatly reduces the boiling point of the liquid that needs to be expelled, so vacuum drying can be easily applied to thermosensitive substances; for samples that are not easy to dry, such as powder or other granular samples, vacuum drying can effectively shorten the drying time. Under vacuum or inert conditions, the possibility of thermal explosion of oxides is completely eliminated; powder samples will not be blown or moved by flowing air. If your samples are the above, you can choose a vacuum drying oven. In addition, ordinary samples can choose a forced convection oven.
