Four ring experimental freeze dryer

Four ring experimental freeze dryerLGJ-24C

Four ring experimental freeze dryerTechnical features:

1. The control software system is Android system, and the freeze-drying process is automatically controlled by programmable programs, which can be switched to manual operation in real time to achieve full parameter control of the freeze-drying process. During operation, the system automatically monitors, detects, records and stores relevant data, and can store multiple fixed or user-defined programs. It can be monitored, tested and maintained through the standard remote system, supporting big data and smart laboratory construction;

2. Continuous recording of real-time data, drawing of freeze-drying curves, storing data once per minute (with adjustable storage interval), standard recording of 100000 times, data storage capacity for 3 years (optional), equipped with data mobile storage USB serial port;

3. The product production has passed the ISO quality management system, obtained the EU CE certification, and the control system human-machine interface complies with NEMA (International Electrical Manufacturers Association) protection regulations;

4. The system is equipped with various sensors that record and display vacuum degree, cold trap temperature, material temperature, and shelf temperature in real time. It also provides operation error alarms and can provide real-time information alarms and actively protect the operation in case of abnormal temperature and pressure during operation. The system also has a light alarm (optional);

5. It has the function of automatic operation of freeze-drying, equipment vacuum pressure loss, equipment alarm and automatic operation to protect materials. When the temperature of the cold trap is higher than -50 ℃, the vacuum pump cannot be turned on to prevent water vapor from entering and affecting the normal operation of the vacuum pump. It also has the function of vacuum pump maintenance prompt;

6. The material is freeze-dried in situ, and the internal corners, surface roughness, shelf flatness, and internal materials of the freeze-drying chamber meet or exceed the relevant national standards. The shelf can be disassembled, smooth, corrosion-resistant, and easy to clean;

7. The material shelf has a program gradient electric heating function, a special aviation heating film, controlled by PLD, built-in overheating protection, and is safe and reliable; (Excluding LGJ-16C/24C)

8. Adopting imported compressor single machine hybrid refrigeration technology, international standard green and environmentally friendly refrigerant, rapid refrigeration, low cold trap temperature, and strong water capture ability;

9. Equipped with automated frost function;

Optional features:

1. Optional automatic drainage and exhaust, pipeline moisture detection;

2. Optional UPS uninterruptible power supply, providing continuous power supply guarantee for the control system for 20 minutes after sudden power outage. Within 5 minutes, the main circuit will be powered on, automatically determining safety conditions and restoring equipment operation according to the current stage;

3. Optional automatic re pressure aeration system: reduces secondary contamination of the sample, and can be quantitatively (optionally) backfilled with nitrogen or inert gas;

4. Optional vacuum degree adjustment function;

5. Optional eutectic point and melting point testing function to better optimize the sample sublimation process;

6. Optional upper computer control;

7. Optional multi manifold bottle hanging device, freeze-drying bottle (eggplant shaped bottle and wide mouth bottle), ampoule tube freeze-drying rack, ampoule tube sealer, penicillin bottle capping machine, imported vacuum pump, high-speed vacuum pump oil;
