What to do when the vacuum oven leaks
A vacuum drying oven is called a vacuum drying chamber because of its vacuum pump. It can reduce the boiling point of liquid to be expelled in a vacuum environment. It is very practical for thermal-sensitive substances. Some powder or granular samples can also shorten the drying time when using a vacuum drying chamber. A vacuum drying chamber can completely eliminate the possibility of thermal explosion of oxides in vacuum environment. Compared with an ordinary drying chamber relying on air circulation, powder samples will not be blown away during drying. But what should we do when air leakage happens in the process of using? In fact, it's not difficult to solve. Kangheng Instrument Laboratory Equipment Manufacturer tells you how to do it. When the vacuum degree of the drying box reaches the required vacuum degree, the vacuum degree decreases in a short time. After replacing the new vacuum valve and electronic tube, it is still the case. So how to check the remaining? It is difficu...
