Negative Pressure Vacuum Drying Oven

The negative pressure vacuum drying oven reduces the internal air pressure by evacuating air, thereby lowering the boiling point of liquids and enabling rapid evaporation of moisture at low temperatures. It is used for dehydrating heat-sensitive materials, drying samples, and removing solvents, thereby avoiding structural damage to substances caused by high temperatures.
Selection
When selecting, pay attention to the matching of the vacuum range with material characteristics, the corrosion resistance of the inner tank material to suit the sample properties, temperature uniformity to ensure drying effectiveness, the sealing of the observation window to maintain the vacuum environment, and the coordination between the pump's pumping speed and the chamber volume.
