Vacuum freeze-drying technology is also known as sublimation drying. The principle is to freeze a sample containing water in advance, and then sublimate its moisture under vacuum. The original biological, chemical and physical properties of the freeze-dried samples remain basically the same, and they are easy to be stored for a long time. After adding water, the samples can be restored to the state before freeze-drying, and their original biochemical characteristics can be maintained. Therefore, freeze-drying technology is widely used in medicine, food, chemical, biological products and other fields. * Compressor, energy saving and high efficiency, low noise, long life. * Vacuum pump, small volume, pumping speed, low noise, can achieve higher vacuum. * Integrated design, compact structure, easy to use. * Environmentally friendly refrigerant, ODP-O. * With defrosting function, safe and reliable. * The cold trap and operating table are made of stainless steel, corrosion resistant and easy to clean. * The transparent cover of the drying chamber is made of aviation acrylic material, with high strength and no bonding. * Large cold trap opening size, with pre-freezing function, no need for low temperature refrigerator. * Professional gas diversion technology, high freeze-drying efficiency, and uniform ice capture.
