Overview
LICHEN LC-50FT silicone oil heat conduction freeze dryer is a device that uses the principle of sublimation for drying. The device will quickly freeze the dried substance at low temperature, and then make the frozen water molecules directly sublimate and escape in a vacuum environment, thus maintaining the original physical and biological characteristics of the substance. After drying, the substance is porous, the volume is basically unchanged, and it is easy to rehydrate and return to its original state.
Features
1.7 inch color LCD Touchscreen, PID control, display temperature, Vacuum Level, support 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 split structure have strong water capture capacity and short drying time.
4. Equipped with anti-return oil vacuum pump, using international standard KF quick connector connection.
5. The use of imported European Compressor and mixed environmental protection refrigerant, rapid cooling, low temperature.
6. Cold trap with pre-freezing function, can replace the low temperature refrigerator.
7. Built-in heat exchanger, effectively reduce the cold trap temperature and enhance 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 new material freeze-drying Linear dispersion through manual mode.
11. With vacuum automatic control heating output function to avoid material collapse caused by excessive heating.
12. Add nitrogen gas charging valve, which can be filled with nitrogen or inert gas for drying and holding.
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
Vacuum freeze drying is a technology that uses the principle of sublimation for drying. This technology quickly freezes the dried substance at low temperature, and then in a vacuum environment, the frozen water molecules are directly sublimated into water vapor and escape. The substance is always in a frozen state before drying, the ice crystals are evenly distributed, and the sublimation process will not condense, avoiding side effects such as foam and oxidation.
