Laboratory vacuum freeze dryer
The principle of freeze-drying is based on the change, mutual transformation and coexistence of the three states of water (solid, liquid and gaseous). When water is at the triple point (temperature is 0.01°C, water vapor pressure is 610.5pa), Water, ice, and water vapor can coexist and balance each other. In a high vacuum state, the principle of sublimation is used to make the moisture in the pre-frozen material directly sublime into water vapor in the ice state without melting the ice, thereby achieving the purpose of freeze drying.
