Item: High Quality Vacuum freeze dryer laboratory lyophilizer
Model: LGJ-15E, LGJ-22E, LGJ-30E
Features
1. Structural design that complies with biopharmaceutical standards. The inner fillet, surface roughness, shelf smoothness and cavity internal materials of the freeze-dried cavity meet the pharmaceutical standards.
2. The control system is stable and reliable. Adopt PLC programmable logic control system and 7-inch color touch screen, the system runs more stable and reliable, human-computer interaction friendly.
3. Display and record vacuum degree, cold trap temperature, material temperature and shelf temperature in real time and form freeze-drying curve, store data every minute, continuously record material and equipment status data, support data offline browsing, analysis, printing and storage, and configure USB communication interface.
4. Freeze-drying process can be controlled: Freeze-drying process is automatically controlled by programmable program. Semi-automatic or full-automatic control can be switched in real time to realize the whole process parameter control of freeze-drying process.
5. Water capture efficiency and capacity: stainless steel inner - wound water capture device, water vapor channel unobstructed, material freeze-drying consistency is good
6. Intermediate medium circulation technology. Shelf gradient temperature control, plate temperature uniformity, strong controllability, flat plate, good heat and cold conduction
7. Double cascade refrigeration technology. The original imported fully enclosed compressor unit and the international standard green environmental protection cold coal are adopted to achieve rapid refrigeration, low cold trap temperature and strong water capture capacity.
8. With the compressor secondary start delay protection and pressure overload protection system.
9. The drying chamber adopts high-pressure, low-temperature-resistant aerospace acrylic material with high transparent door to observe the whole process of material freeze-drying change.
10. The rest plate silicone oil refrigeration and heating, with temperature, speed adjustable, controllable, to achieve in-situ pre-freezing and sublimation function.
11. Configure the interface of the negative pressure aeration system. Built-in 0.2μm filter element to reduce secondary pollution of the sample, backfilling with nitrogen or inert gas
12. Cold trap has automatic frost function.
13. Optional clean room installation, and provide clean room installation solutions.
14. Optional vacuum adjustment function to realize freeze-drying process exploration.
15. Optional eutectic point online test function to better optimize the sample sublimation process;
16. Optional wireless remote real-time monitoring and chart recording of the computer.
