Lyophilization is a freeze-drying method used to ensure the long-term preservation of biological and chemical substances. In this process, the sample is first frozen, and then water is removed by sublimation—direct transition from the solid (ice) phase to the vapor phase—under low pressure. This removes nearly all the water from the substance, resulting in a dry, stable product. Lyophilization is particularly preferred for heat-sensitive materials because water removal at low temperatures does n
