Find out More Jan 15, 2024When using a vacuum oven to test products, you need to pay attention to the following points: 1. The sample is placed in a vacuum oven and vacuumed to remove the air components that can be extracted from the material of the sample. If the sample is heated first, the air will expand when heated. Since the sealing of the vacuum oven is very good, the huge pressure generated by the expanding air may cause the tempered glass of the observation window to burst. This is a potential danger. This danger...
