This GZL-2 water-cooled 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 maintain their chemical and biological characteristics after being watered. Main features of the GZL-2 water-cooled Pilot Freeze Dryer 1. It is our company's patented product . Freezing and drying is finished 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.
