Vacuum freeze dryer category
Lab lyophilizer (small lyophilizer) can be divided into: ordinary lyophilizer, gland lyophilizer, multi-manifold lyophilizer, and multi-manifold lyophilizer.
Ordinary lyophilizer: The materials are bulked in the material tray, which is suitable for freeze drying of food, Chinese herbal medicine and powder materials.
Gland-type freeze dryer: suitable for drying of bottled materials in vials. When preparing for freeze-drying, separate the materials into vials as required. After the caps are floated and freeze-dried, the capping mechanism is used to compact the bottles. The cover can avoid secondary pollution and re-adsorb moisture, which is easy to store for a long time.
Multi-manifold lyophilizer: Install a flask outside the drying chamber to dry the material that is spin-frozen on the inner wall of the bottle. At this time, the flask is connected to a manifold outside the drying box as a container. With the multi-manifold switch device, the flask can be removed or installed at any time as needed without stopping the machine.
Multi-manifold gland type freeze dryer: Combining the characteristics of gland type and multi-manifold type.
I. Main features:
1. This machine adopts international brand Secop (formerly Danfoss) compressor for refrigeration, fast cooling and low temperature of cold trap.
2. It adopts 7-inch true color touch LCD screen control system, which is easy to operate and powerful.
3. Industrial embedded operating system, ARM9 core control circuit design, 32M memory 128M FLASH, fast operation response speed, large amount of stored data.
4. The control system automatically saves the freeze-dried data and can view it in the form of real-time curves and historical curves. The entire freeze-drying process is clear and clear.
5. The drying room adopts colorless transparent polycarbon drying room. The samples are clear and intuitive, and the whole process of lyophilization can be observed.
6. Material tray heating is provided with over-temperature protection function. Compressor overcurrent and overload delay protection.
7. This machine can store multiple freeze-dried curves, and use U disk to extract data to the computer, and use the PC software to browse and print in the computer and many options.
8. The control system has 36 freeze-drying curve scheme options, each scheme contains 40 sections of temperature control settings, which can realize the freeze-drying process parameter recording of a variety of materials. .
9. The company's unique point-shaped heating temperature curve calculation method, the heating is more stable, without overshoot, and the temperature control is more accurate.
10. Equipped with inflation valve, can be filled with dry inert gas;
11.The temperature of the separator is adjustable, controllable, groping, pilot test and product
