Character
High flatness sample shelf:
Silicone oil thermal conductive shelf, high-precision processing method of upper and lower clamping, shelf temperature uniformity can reach ±0.5°c
Integrated cavity:
Integrated chamber, the shelf and cold trap are located in the same chamber, the steam conduction is faster and the freeze-drying effect is better
Refrigerating and heating control system:
Using thermally conductive silicone oil with a high temperature range and precise PID control algorithm, the control accuracy can reach ±0.5°C. Sample shelf temperature range: -70°C~ +80°C
Freeze-drying endpoint testing system:
The pressure comparison method is used to determine the freeze-drying end point. The freeze-drying end point test can be automatically performed after the analytical drying stage to ensure that the moisture content of the material reaches the standard requirements.
Vacuum precise control and adjustment system:
The sublimation and analytical drying processes are controlled and adjusted with high precision to make the freeze-drying process warmer and the sample sublimation more reliable.
Pulse backfill system:
Three backfilling modes can be selected: slow, medium and fast, which avoids the problem of effective substances being blown away and lost due to the aeration of granular and flocculent materials after freeze-drying.
Manual automatic mode selection:
Manual mode is used to explore process parameters (strong human intervention), automatic mode is used in the mature stage of the process, one-click operation, simple and convenient
Data recording and analysis system:
Through the PC host computer, all operating parameters and background parameters of the equipment can be recorded in real time, and all parameter action changes and action changes of operating components can be recorded.
Freeze-drying process recipe storage function:
The host can store 60 sets of fixed or user-defined freeze-drying process recipes, and the PC can store >10,000 programs (depending on the computer hard drive)
Eutectic point test function:
The eutectic point temperature of the product can be tested offline and online, and the spectrum can be analyzed manually or automatically (optional)
Remote control system:
The operating status of the device can be monitored remotely, and the device can be monitored in real time via WiFi or the cloud.
Mobile phone monitoring system:
You can monitor the operating status of the equipment with your mobile phone, which is simple and convenient (optional)
Cold trap defrost system:
The hot air defrosting method has high safety performance; the defrosting speed is fast, which solves the inconvenience caused by traditional immersion defrosting.
