LGJ-24D Vacuum Freeze Drier

Vacuum Freeze Drier

Model No.: LGJ-24D

Features

1.Equipped with Android software control system, and the freeze-drying process is automatically controlled by programmable controller (optional), 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. Multiple fixed or customized programs can be recorded, and monitoring, testing and maintenance can be reached through the standard remote system.

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.Freeze-drying in situ, unique equipment design structure, can be applied to all laboratory materials freeze-drying experiment, freeze-drying chamber inside the corner, surface roughness, shelf flatness, the chamber inside the material meet pharmaceutical standards, smooth corrosion resistance and easy to clean.

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

7.Adopts imported compressor double stack refrigeration technology, international standard green refrigerant, rapid refrigeration, low cold trap temperature, strong water capture capacity.

8.Equipped with auto-defrosting function.

Optional Functions

1.UPS (uninterruptible power supply).

2.Optional automatic pressure and aeration system: reduce the secondary pollution of the sample, can be quantitative (optional) backfill nitrogen or inert gas.

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

4.Optional vacuum adjustment function.

5.Eutectic point eutectic point test function, better optimize the sample sublimation process.

6.Upper computer control.

7.Optional: 8 multi-manifold bottle hanging device, freeze-drying bottle (nightshade bottle and wide mouth bottle), 8 ampoule tube freeze-drying frame, ampoule tube sealer, Xiling bottle capping machine, imported vacuum pump, high-speed vacuum pump oil.
