Electrically heated freeze dryer

Vacuum freeze dryer is widely used in medical, pharmaceutical, biological research, chemical and food fields. Items treated by freeze-drying are easy to be preserved for a long time, and can be restored to the pre-freeze-drying state and maintain the original biochemical characteristics after adding water. LGJ-12S freeze-dryer is a small vertical freeze-drying equipment. It has shelf heating and programmable functions. It is suitable for laboratory use or a small amount of production, and can meet the requirements of conventional freeze-drying in most laboratories.

Characteristics of technical parameters of freeze dryer:

1. Integral structure design, small size, no external flange, easy to use, no leakage.

2. All materials in contact with the product are inert materials to meet the requirements of GLP.

3. Cold trap and operating table are made of stainless steel, which is corrosion-resistant and easy to clean.

4. All stainless steel inflatable (drainage) valves designed and manufactured by our company are safe, anticorrosive and leak-free.

5. The cold trap has large opening, no inner coil, with sample pre-freezing function, and no cryogenic refrigerator is needed.

6. Specialized gas diversion technology, uniform cold trap ice capture, ice capture ability.

7. International well-known brand compressor, high efficiency and energy saving, long service life, low noise.

8. Well-known brand vacuum pump, high pumping speed, to achieve higher vacuum limit.

9. Vacuum pump protection function, can set the starting cold trap temperature of vacuum pump, protect the service life of vacuum pump.

10.7 inch real color industry embedded touch screen + SH-HPSC-II modular controller, high control accuracy, stable and reliable performance.

11. The specially designed FD-EMB control system can preserve hundreds of sets of technological formulas, each of which contains 50 temperature control sections, so as to improve the technological optimization rate.

12. Intelligent data recording system, real-time record and display cold trap temperature curve, sample temperature curve, vacuum curve, derived data can be browsed and printed by computer and a variety of operations.

13. Temperature control system of safety voltage (36V) for plate heating can control the heating rate.

14. Flexible manual + automatic control mode, manual groping process, automatic batch production.

15. Real-time alarm display and historical alarm inquiry function to facilitate fault diagnosis and equipment maintenance.

16. User level and password can be set, and operation management can be decentralized.

17. Powerful sensor calibration function to ensure long-term use of measurement accuracy.
