BK-FD18P Vertical Freeze Dryer
Vacuum freeze-drying technology, also known as lyophilization, is a process that involves pre-freezing a water-containing sample, followed by the sublimation of moisture under a vacuum. The original biological, chemical, and physical properties of the freeze-dried samples remain virtually unchanged, making them easy to store for long periods. Upon the addition of water, the samples return to their pre-lyophilization state, retaining their original biochemical characteristics. Consequently, freeze-drying technology is widely used in the food, chemical, biological, and other sectors.
