Other Details :
The vacuum oven consists of a jacketed vessel sufficiently stout in construction to withstand vacuum within the oven and steam pressure in the jacket. In addition, the supports for the shelves form part of the jacket, giving a larger area of conduction heat transfer.
The oven can be closed by the door that can be locked tightly to give an airtight seal. The oven is connected through condenser and receiver to a vacuum pump, although if the liquid to be removed is water and the pump is of the ejector-type that can handle water vapor, the pump can be connected directly to the oven.
