When using the Pilot Freeze Dryer for the first time, all parts of the instrument must be thoroughly cleaned. The stainless steel parts are cleaned with ethanol and the plexiglass is washed with saline. The ampoule is cleaned with an ultrasonic cleaner.
Pre-freezing must be carried out before lyophilization. If you need to prepare a low-temperature refrigerator, a temperature of minus 40 degrees Celsius, or a low-temperature refrigerator of minus 80 degrees Celsius, put the items to be dried in a low-temperature refrigerator or liquid nitrogen, or use the Songyuan Huaxing brand. The lyophilizer has a built-in ultra-low temperature refrigerator to pre-freeze the cold well, which saves the cost of purchasing a low-temperature refrigerator. It usually takes about four hours. It can be observed directly from the outside, and the freeze-drying experiment can be carried out after the article is completely frozen. Quickly move the items into the Pilot Freeze Dryer tray to ensure freeze-drying effect. For example, if you purchase Songyuan Huaxing's in-situ pre-freeze freeze dryer, you don't need to move the material to the tray. You can use Songyuan Huaxing to freeze. The intelligent operation of the dryer integrates pre-freezing-vacuum-heating-drying-removing. Solved the tedious routine operation. The main unit and the vacuum pump are connected by a green vacuum tube, and the joint uses an international standard clamp. In order to effectively prevent air leakage, this type of clamp is specially designed with a sealing rubber ring in the clamp. In the method of preventing air leakage, apply a proper amount of vacuum grease on the rubber ring and then clamp it with a clamp to make the joints fit closer together. If the clamp is not clamped, air leakage will occur, causing the instrument panel to display a digital display value greater than 20 Pa while vacuum is being drawn. The vacuum pump and the Pilot Freeze Dryer glass cover should be checked for air tightness.
The Pilot Freeze Dryer has two power outlets on the right side panel. One connects the vacuum pump's power cord to the main unit, and then plugs the main power supply on the second Pilot Freeze Dryer.
Before the vacuum pump is running, it must be checked whether vacuum pump oil is added, otherwise it will not operate normally. The oil level should not be lower than the center line of the oil mirror. Generally, after the oil level is stable, look at the observation window 1/2 "oil surface" 2/3 vacuum pump has a strong shaking when it is used at the beginning, and white smoke (because pine Yuanhuaxing freezes dry and has more air in the warehouse. It will gradually become stable. If the air tightness is not good, apply some vacuum grease to the sealing rubber ring above the cold trap, spin the plexiglass cover onto the rubber ring, and test the air tightness by opening the Pilot Freeze Dryer vacuum pump. To ensure the integrity of the Pilot Freeze Dryer gas seal. The normal material drying process can be completed in a cycle of about 24H. There are also some materials with more water, or contain sugar, viscous materials, need to increase the drying time, and also according to the thickness of the material placed on the tray, matching the Songyuan Huaxing freeze dryer The power size is determined. When taking the material, first open the inflation valve (Remark: first enter a small amount of outside air, wait for the vacuum gauge to display about 200 in the fully open inflation valve, turn off the vacuum pump) Finally, take out the material from the drying chamber of Songyuan Huaxing Freeze Dryer, Finished the drying process.

  This GZL-4 Pilot Freeze Dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production ,etc. After the freeze drying process,a long term preservation is much easier. They can be restored to the original state and mantain their chemical and biological characteristics after being watered.
  Freezing and drying process of LGL-4  are completed in the same place (patented product). It changes the cumbersome operation of the drying process in the past, prevents the contamination of materials, and realized dry sublimation automatically. The model is equipped with shelf heating and has programmable functions. It can memorize freeze-dried curves for users to observe the lyophilization process of materials.

 GZL-4 Pilot Freeze Dryer main features

1. It is our company's patented product . Freezing and drying is completed in the same place. It is easy to operate,and have a good drying effect.
2. Patented gas diversion technology, uniform ice catching in cold traps, and strong ice catching capability.
3. Internationally renowned brand compressors, high efficiency, long life, low noise.
4. Separator patented technology and partition temperature fuzzy control technology, the shelf temperature difference is small, the temperature control accuracy is high, and the drying effect is even.
5. The freeze-drying curve optimization control technology can control the cooling rate in the pre-freeze phase, and at the same time, it can control the sample heating rate and the current stage vacuum degree in the sublimation and analytical drying stages.
6. The powerful sensor calibration function ensures the long term accuracy  of the measured value.
7. 7-inch true color industrial embedded touch screen + SH-HPSC-II modular controller, high control accuracy, stable and reliable performance.
8. The professionally designed FD-PILOT control system can save hundreds of process recipes. Each recipe contains 50 temperature control zones to improve the process optimization rate.
9. Intelligent data recording system, real-time record and display the cold trap temperature curve, sample temperature curve, vacuum curve, export data can be viewed through the computer and print a variety of operations to facilitate process optimization and verification of drying effect.
10. Flexible manual + automatic control, manually used for groping the process, automatically used for mass production.
11. Real-time alarm display and historical alarm query function to facilitate fault diagnosis and equipment maintenance.

12. Vacuum adjustment during drying operation to avoid foaming and blowing of special materials and improve drying efficiency.
13. Setting the user level and password , and decentralizing operation management
