As a critical piece of equipment, the vacuum pump plays a vital role in modern industry and scientific research. It creates a vacuum environment by evacuating gas from a sealed container using mechanical, physical, chemical, or physicochemical methods. Vacuum technology is widely applied in sectors such as semiconductor manufacturing, electronics, chemicals, pharmaceuticals, and food processing, serving as an indispensable technical means for achieving high-precision processes.
The vacuum pump is the core component of a freeze dryer. It continuously removes gas and water vapor from the chamber, creating and maintaining a high-vacuum, low-temperature, low-pressure environment. This ensures that ice crystals in the material can directly sublimate, providing crucial power for achieving efficient and stable freeze-drying processes. Its performance directly affects freeze-drying efficiency and product quality.
How to choose the vacuum pump used in the laboratory is a problem that plagues many users. After buying a vacuum pump, many users will encounter the vacuum gauge to observe that the vacuum is not enough (not enough suction), the pumping speed is too slow, and it is used in a relatively closed room. Excessive noise, or oil mist when the pump is in use, can not be used normally, and other problems. These problems are often related to the selection.
