What is a vacuum oven?
A vacuum oven is a chamber that controls two parameters: temperature and pressure. It is mainly used to dry samples at lower temperatures.
Lowering the pressure (creating a vacuum) also lowers the evaporation point of water and other liquids. At 50 mbar, for example, water boils at just 33 °C.
When your samples are temperature-sensitive. A vacuum oven dries them at lower temperatures — for example, biologically active samples you want to dry at around 30 °C.
A vacuum pump reduces the pressure. Under vacuum, there is very little heat transfer by convection, so the main heat-transfer method in a vacuum oven is conduction, using heated shelves (thermoshelves).
