Overview
The LC-12N-80D vertical freeze dryer is a device that utilizes vacuum freeze drying technology. This technology dries by rapidly freezing the dried substance at low temperature, and then directly sublimating and escaping the frozen water molecules in a vacuum environment. During the drying process, the substance is always in a low temperature freezing state, and the ice crystals are evenly distributed, avoiding condensing, foam, oxidation and other side effects. Finally, the drying product is porous sponge-like, basically unchanged in volume and easy to rehydrate, which can effectively prevent the physical and biological denaturation of the substance.
Features
1. Equipped with 7-inch color LCD Touchscreen, using PID control, can clearly display temperature, Vacuum Level, and support Linear dispersion browsing, intuitive and easy to use.
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, the connection with the host adopts international standard KF quick connector, and the connection is 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 the function of pre-freezing, which can be used instead of the low temperature refrigerator.
6. Built-in high-efficiency heat exchanger, effectively reducing the cold trap temperature and 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 the vacuum environment created by the device, the water molecules (ice crystals) in the frozen substance are directly sublimated from the solid state to water vapor without passing through the liquid state. This water vapor is trapped in a cold trap, thus realizing the dehydrated drying of the substance. The whole process of the substance is always in a low temperature freezing state, and the structure is well preserved.
Applications
Biological products, medicines, food, chemical materials, scientific research experiments
