The vacuum desiccator uses vacuum pump to pump air and humidity to reach the vacuum state of the working room. The drying rate of materials is greatly accelerated and energy saving. Therefore, it is suitable for drying unstable or heat sensitive materials. Vacuum desiccator has good sealing performance, so it is also suitable for drying materials that need to recover solvents and contain strong irritant and toxic gases. This product is widely used in all kinds of laboratory, chemical, food, medical and health, precision instrument, fine chemical industry and other industries.
