Product Description

Laboratory Vacuum Freeze Dryer


Laboratory vacuum freeze dryers are widely used in the fields of medicine, pharmaceuticals, biological research, chemicals and food. The lyophilized articles are easy to store for a long time, and can be restored to the state before lyophilization and maintain the original biochemical characteristics after adding water. The LGJ-18 freeze dryer is suitable for laboratory use and meets the requirements of routine lyophilization in most laboratories.

1. One-piece structure design, small size, no external flange, easy to use, no leakage.
2. All materials in contact with the product are made of inert materials to meet the requirements of GLP.
3. The cold trap and the operating table are made of stainless steel, which is corrosion-resistant and easy to clean.
4. All stainless steel inflatable (discharge) valve design, production, safety, anti-corrosion, no leakage.
5. The cold trap has a large opening, no inner coil, and sample pre-freezing function, no need for a low temperature refrigerator.
6. Specialized gas guiding technology, cold trap for uniform ice trapping and strong ice trapping ability.
7. Internationally renowned SECOP (DANFOSS) brand compressors, high efficiency, energy saving, long service life and low noise.
8. Well-known brand vacuum pump, pumping speed, to achieve a higher ultimate vacuum.
9. Vacuum pump protection function, can set the vacuum pump to start the cold trap temperature and protect the service life of the vacuum pump.
10. Professional design FD-LAB freeze dryer control system + SH-HPSC-I modular controller, with high reliability and stability.
11. Intelligent data recording system, real-time recording and display of cold trap temperature curve, sample temperature curve, vacuum degree curve, export data can be browsed by computer and printed.
