Working Principle And Classification Of Vacuum Pumps For Freeze Dryers
The vacuum pump is the core component of a freeze dryer. It continuously removes gas and moisture 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.

The Maintenance Of Low-temperature Circulating Pump
The cryogenic coolant circulation pump is a combination of a circulating pump and a cryogenic cooling pump. It is a good auxiliary equipment for vacuum distillation and vacuum concentration. It is especially adapted to be equipped with a rotary evaporator, which not only reduces the use space, but also reduces the vacuum degree and saves water resources. It is widely used in modern laboratories.

How to choose a vacuum pump in the laboratory?
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.
