Overview
LICHEN LC-12N-80B vertical freeze dryer is a device that uses the principle of sublimation for drying. This technology will quickly freeze the dried substance at low temperature, and then make the frozen water molecules directly sublimate and escape in a vacuum environment. The substance is always in a frozen state before drying. After drying, it is porous and the volume is basically unchanged. It is easy to rehydrate and prevent physical and biological denaturation to a greater extent.
Features
1.7 inch color LCD screen, PID control, display temperature, Vacuum Level, Linear dispersion browsing, clear and intuitive.
2. The drying chamber is covered with colorless transparent plexiglass, which can observe the whole process of freeze-drying.
3. Equipped with anti-return oil vacuum pump, connecting with the host using international standard KF quick connector, simple and reliable.
4. Using the original imported Compressor from Europe, with mixed environmentally friendly refrigerant, the refrigeration is rapid and the freezing temperature is low.
5. The cold trap has a pre-freezing function, which can replace the low temperature refrigerator.
6. Built-in heat exchanger, effectively reduce the cold trap temperature, strong water capture capacity.
7. Equipped with a nitrogen gas charging valve, which can be filled with nitrogen or inert gas for drying.
Principle
Vacuum freeze drying uses the principle of sublimation for drying. First, the dried substance is quickly frozen at low temperature, and then in a vacuum environment, the frozen water molecules are directly sublimated into water vapor and escape. During the whole process, the substance is always in a low temperature freezing state before drying, and the ice crystals are evenly distributed. The sublimation process will not condense due to dehydration, avoiding side effects such as foam and oxidation.
