Vacuum oven also referred as Vacuum Drying Oven & Vacuum Dryer, is used for performing drying operations which generally comprise of removal of moisture from materials which are heat sensitive &/or highly hygroscopic in nature

The vacuum ovens avoids damage to the sensitive material while drying in vacuum as rapid temperature overshooting is avoided as the working principle behind the operation of a vacuum oven involves substantially lowering the ambient pressure to decrease the boiling point of the liquid in the substance via the use of a vacuum pump.

Vacuum drying is one of the most effective and gentle drying methods available. The aim of this method is to gently dry a high-grade product that contains water or a solvent without endangering the materials. Drying in a vacuum drying chamber is particularly recommended for compounds containing flammable solvents. Due to the oxygen in the air in particular, these compounds often develop an explosive atmosphere during the drying process. This is prevented when dried in a vacuum drying chamber. Vacuum drying also minimizes the risk of scaling or oxidation residue.
