What about the refrigerant leak in the laboratory freeze dryer?
Refrigerant, also known as refrigerant, is commonly known as snow in some areas of the South. It is a working substance that continuously circulates in a refrigeration system and undergoes its own state change to achieve refrigeration. The refrigerant absorbs heat in the evaporator by heat of a cooling medium (water or air, etc.), and transfers heat to the surrounding air or water in the condenser to condense.

How to choose a suitable freeze dryer?
The principle of a freeze dryer is a technical method of preliminarily freezing an aqueous article and then sublimating its water under vacuum to obtain a dried article. The freeze-dried articles are easy to store for a long time, and can be restored to the state before lyophilization and retain the original biochemical characteristics after adding water.
