Application field: freeze-drying is a technology that uses the principle of sublimation to dry. It is the process of rapidly freezing the dried substances at low temperature, and then sublimating the frozen water molecules directly into water vapor overflow in an appropriate vacuum environment. The substance is always at a low temperature (frozen state) before drying, and ice crystals are evenly distributed in the substance. During the sublimation process, concentration will not occur due to dehydration, and side effects such as foam and oxidation caused by water vapor are avoided. The lyophilized products are spongy, non-shrinkage, good rehydration and low moisture content, and can be stored and transported for a long time at normal temperature after corresponding packaging.

Product features

1.Rapid cooling The temperature of the inner wall of the cold trap is uniform, and the professional gas diversion technology has good water capture effect.

2. The brand Danfoss compressor is adopted, and the single-machine hybrid environmental protection refrigeration technology is adopted.

3. The cold trap sample pre-freezing function is configured, and there is no need to be equipped with an ultra-low temperature refrigerator or treated with liquid nitrogen.
