Four ring laboratory capping device type freeze dryerLGJ-12F

Technical features:

1Four ring laboratory capping device type freeze dryerofThe control software system is Android system, and the freeze-drying process is automatically controlled by programmable programs (optional), 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 custom programs. It can be monitored and maintained through remote systems (optional), 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, shelf temperature in real time, and can query all historical records. Operation error alarm can provide real-time information alarm and actively protect the operation in case of abnormal temperature and pressure during operation, with 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 cold trap chamber and material tray are made of sanitary grade stainless steel material. There are no coils inside the cold trap, which is smooth, corrosion-resistant, and easy to clean. It has material pre freezing function;

7. The cold trap drying chamber is made of aviation grade organic glass material that is resistant to high pressure and low temperature, and is covered with an explosion-proof layer film (optional). The entire freeze-drying process of the material can be observed;

8. The material shelf has a program gradient electric heating function (except for LGJ-25C, LGJ-12F/15F/25F can be optionally selected), a special aviation heating film, controlled by PLD, built-in overheating protection, safe and reliable;

9. Adopting imported compressor single machine hybrid refrigeration technology (LGJ-12F/15F/25F models adopt dual compressor cascade refrigeration technology), it has multiple protections such as high oil pressure, overheating, and delayed start. It is an international standard green and environmentally friendly refrigerant, with fast refrigeration, low cold trap temperature, and strong water capture ability;

10. Equipped with program controlled automated frost function;

Optional features:

1. 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;

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

3. Optional automatic program control re pressure and gas mixing back filling system to reduce secondary contamination of samples. Nitrogen or inert gas can be quantitatively (optionally) backfilled. After freeze-drying is completed, the vacuum pump stops and the re pressure and gas mixing system automatically starts. The vacuum system is interlocked with the re pressure and gas mixing back filling system to prevent the vacuum pump oil from flowing back into the cold trap and drying chamber and contaminating the freeze-dried materials;

4. Optional vacuum degree adjustment function;

5. Optional upper computer control;

6. Optional capping device;

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, eutectic point tester, inert gas inflation port, imported vacuum pump, high-speed vacuum pump oil;
