What are the differences between a vacuum oven and a conventional oven?
The main difference between a vacuum oven and a conventional oven lies in their working pressure. Conventional ovens operate at atmospheric pressure, heating through air convection, making them suitable for routine drying tasks. In contrast, vacuum ovens are evacuated to low pressure to reduce air presence, primarily relying on thermal radiation for heat transfer. This makes them ideal for processing heat-sensitive, oxidation-prone materials or those requiring thorough drying.
