Vacuum Oven

A vacuum oven reduces the internal pressure by evacuating air, lowering the boiling point of liquids to allow rapid evaporation of water or solvents at low temperatures. It is used for drying heat-sensitive materials, dehumidifying electronic components, and processing chemical samples to avoid oxidation or component degradation caused by high temperatures.
Selection
When selecting, consider the compatibility of the temperature range with the material's heat resistance, and ensure the vacuum level meets process requirements. The chamber size should be determined based on the volume of the items to be processed, and the heating method influences the uniformity of the temperature field. Pay attention to the vacuum pump's pumping speed and ultimate vacuum specifications, as well as the material of the door sealing strip and the ease of operation of the control system.

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.

This makes them ideal for processing heat-sensitive, oxidation-prone materials or those requiring thorough drying.
