Overview
LC-20F silicone oil heat conduction freeze dryer is a drying equipment using the principle of sublimation. It will be dried material at low temperature rapid freezing, and then in a vacuum environment to freeze the water molecules directly sublimation escape, so as to maintain the original structure and activity of the material, drying material is porous, easy to rewater to restore the original state.
Features
1.7 inch color LCD screen, PID control, display temperature, Vacuum Level, Linear dispersion browsing.
2. The freeze-drying chamber adopts transparent organic Glass door panel, and the process can be seen.
3. The drying chamber and the cold trap are split structures, with strong water capture capacity and short drying time.
4. Equipped with anti-return oil vacuum pump, connected by KF quick connector.
5. The use of imported European Compressor and mixed environmental protection refrigerant, rapid cooling, low temperature.
6. The cold trap has a pre-freezing function, which can replace the low temperature refrigerator.
7. Built-in heat exchanger, effectively reduce the cold trap temperature, strong water capture capacity.
8. In situ freeze-drying (pre-freezing and drying are integrated) can be achieved.
9. The silicone oil heat conduction method is adopted, and the top layer is equipped with a silicone oil Hot Plate to make the drying indoor temperature more uniform.
10. Equipped with manual and automatic Operating Modes, you can explore the lyophilized Linear dispersion of new materials through manual mode.
11. With vacuum automatic control heating output function to avoid the material collapse due to excessive heating.
12. Add nitrogen gas charging valve, which can be filled with nitrogen or inert gas for drying.
13. 20 programs can be stored, each program can be set to 36 segments, parameters can be modified during operation and drying Linear dispersion can be recorded.
14. With hydraulic gland function, it is convenient to cap the bottle after drying (model with T).
Principle
The equipment is based on vacuum freeze drying technology. First, the dried material is quickly frozen at low temperature, so that the water in it forms ice crystals. Then in a vacuum environment, the ice crystals are directly sublimated into water vapor without going through the liquid state, and the water vapor is captured by the cold trap. The whole process of the material is always in a low temperature state, avoiding side effects such as condensation, foam, oxidation, etc., thereby maintaining the physical and biological characteristics of the substance.
Applications
Biological products, medicines, food, chemical materials, scientific research experiments
