Product Description
The basic principle of freeze drying is based on the three-state change of water. Water has solid, liquid and gaseous states, and the three states can be converted to each other and can coexist. When water is at the triple point (temperature of 0.01℃, water vapor pressure of 610.5Pa), water, ice, and water vapor can coexist and balance each other. Under the high vacuum state, using the principle of sublimation, the moisture in the pre-frozen materials will be directly sublimated in the ice state to remove water vapor without melting the ice, so as to achieve the purpose of freeze drying. In-depth analysis is suitable: Nano thin film materials , Microelectronic materials, catalysts, tribochemistry, surface and interface research of polymer materials.
It is used for freeze-drying and bacterial protection in the fields of biological research, medicine and pharmacy, chemical industry, food processing, colleges and universities.
