LGJ-50D Vacuum Freeze Drier

Vacuum Freeze Drier

Model No.: LGJ-50D 

Features

1.Equipped with LINUX software control system, and the freeze-drying process is automatically controlled by programmable controller, which can be switched to manual operation in real time to realize the whole parameter control of the freeze-drying process. In the operation process, the system automatically monitors, detects and records the data. Record process ≥ 100, with each process ≥ 36, with 3 levels limited management. Multiple fixed or customized programs can be recorded, and monitoring, testing and maintenance can be reached through the standard remote system with record trace function.

2.Continuously record real-time data, drawing freeze-dried graphs, store data each of one minute (adjustable). The unit is equipped with USB port for data download and edition.

3.CE and NEMA certificated.

4.The system is equipped with a variety of sensors, displays the real-time record of vacuum level, cold trap temperature, material temperature, shelf temperature. A active protection system will automatically turned on while the unit receiving the abnormal temperature and pressure from the unit, which the abnormal information is caused by operation error alarm.

5.The inner corners, surface roughness, shelf flatness and inner materials of the freeze-dried cavity all meet or exceed the relevant national standards.

6.The material is freeze-dried in situ, the cold trap cavity and the material tray are sanitary stainless steel materials, there is no coil in the cold trap, the shelf can be disassembled, smooth and corrosion-resistant and easy to clean, the shelf spacing can be adjusted freely by adjusting the number of shelf layers according to the height of the material container, and the freeze-dried area can be arranged arbitrarily.

7.Material shelf with program gradient electric heating function, special aviation heating film, using PLD control, built-in overheating protection, safe and reliable.

8.The external cold trap improves the water catching capacity of the equipment, reduces the interference of the cold trap temperature on the material during the freeze-drying process, ensures the consistency of the material freeze-drying quality and the stability of the experimental data, improves the freeze-drying efficiency and reduces the energy loss.

9.Adopt imported compressor single machine mixed refrigeration technology, international standard green refrigerant, rapid refrigeration, low cold trap temperature, strong water capture capacity.

10.Equipped with auto-defrosting function.

Optional Functions

1.UPS (uninterruptible power supply).

2.Optional automatic pressure aeration system: reduce sample secondary pollution, Optional quantitative backfill nitrogen or inert gas.

3.Vacuum level adjustable.

4.The eutectic point test function is selected to optimize the sublimation process of samples.

5.Optional upper computer control.

6.Visual alarm (indicator light alarm) is optional.

7.Optional: 12 multi-manifold bottle hanging device, freeze-drying bottle (nightshade bottle and wide mouth bottle), 12 ampoule tube freeze-drying frame, ampoule tube sealer, Xiling bottle capping machine, imported vacuum pump, high-speed vacuum pump oil.
