Freeze drying technology has strong drying ability and is now widely used in many fields. Suitable for high-precision research such as biological sample freeze-drying experiments, industrial material freeze-drying experiments, fine chemical sample freeze-drying experiments, soil freeze-drying research, etc.

Rare earth metals are a key component of the green economy, crucial for hybrid vehicles, wind turbines, and many other green technology innovations. Nowadays, the value of rare earth mining and research is becoming increasingly prominent, and correspondingly, higher requirements are placed on research equipment.

The Rare Earth Research Institute of the Chinese Academy of Sciences is a national scientific research institution focusing on rare earth science and technology innovation. Facing the major needs of national strategy and industrial development, it develops green mining, dressing and metallurgy and efficient utilization of resources to develop new materials, strengthens ecological environment protection, and ensures the green and sustainable development of China's rare earth industry.

In order to conduct more precise research on rare earth materials, the Rare Earth Research Institute of the Chinese Academy of Sciences has purchased two vacuum freeze dryers - the LGJ-12A standard vacuum freeze dryer and the LGJ-12A standard multi manifold vacuum freeze dryer - from Beijing Sihuan Qihang.

The LGJ-12A model freeze dryer is an experimental freeze dryer developed and produced by Beijing Sihuan Qihang. It is small in size and can be placed on laboratory countertops. The multi tube type can be equipped with wide mouthed bottles or eggplant shaped bottles according to different experimental samples. The standard model of this equipment is equipped with 4 layers of material trays, with a freeze-drying area of up to 0.12 square meters, a cold trap temperature of up to -65 ℃, and a maximum vacuum degree of<1Pa.

The control system can automatically save freeze-drying data and view it in real-time and historical curve forms, displaying working time, condenser temperature, sample temperature, and vacuum degree in curve and digital forms. Freeze drying data can be queried and exported on a USB drive. The drying room is covered with high transparency acrylic material that is resistant to high pressure and low temperature, allowing for observation of the entire freeze-drying process. According to special freeze-drying requirements, optional cold trap electric heating defrosting, stacking unit, -80 ℃ cold trap temperature, etc.

Small devices play a big role, and in the future, it is expected that with the support of freeze-drying technology, China's research on rare earth materials will achieve greater results.
