Overview
The vertical freeze dryer LC-12N-80C is a device that uses vacuum freeze drying technology. It completes the drying process by rapidly freezing the dried substance at low temperature and directly sublimating and escaping the frozen water molecules in a vacuum environment. The technology can keep the substance in a frozen state before drying, and the ice crystals are evenly distributed, avoiding the side effects of condensation, foam, oxidation, etc. Finally, the drying product is porous sponge-like, basically unchanged in volume and easy to rehydrate, effectively preventing the physical and biological denaturation of the substance.
Features
1. Adopt 7-inch color LCD Touchscreen, PID control, can display temperature, Vacuum Level, and support Linear dispersion browsing, clear and intuitive.
2. The drying chamber is covered with colorless transparent plexiglass, which is convenient for observing the freeze-drying process throughout the process.
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 be used instead of 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, it can be filled with nitrogen or inert gas after drying to maintain the sample state.
Principle
The device works based on the principle of sublimation. First, the dried substance is rapidly frozen at a low temperature. Subsequently, in a vacuum environment, the ice crystals in the frozen substance do not go through the liquid water stage, directly sublimate into water vapor and are captured by the equipment cold trap, thus realizing drying. The substance is always in a low temperature freezing state during the whole process, and the structure is maintained.
