![]() In the home, lyophilizers are most commonly used to freeze dry foods. Laboratory freeze dryers are commonly used for research in biological and environmental disciplines, as well as in the research and development of many modern medicines. Since the development of these modern freeze-drying techniques, lyophilization technology has continued to advance and has been used for a broad spectrum of applications in a variety of fields. ![]() The first major utilization of freeze drying was during World War II, for the transportation of blood, serum and penicillin. Lyophilization can be achieved in various volumes, from small at-home freeze dryers all the way up to large, production-scale equipment. ![]() This process, called sublimation, along with the minimal heat input that is required, is ideal because of the long-term preservation properties it provides to the integrity of the sample’s biological and chemical structure. With its unique preservation properties, freeze drying has a large variety of applications with an ever-growing list of new uses each year.įreeze Drying is a process in which a completely frozen sample is placed under a vacuum in order to remove water or other solvents from the sample, allowing the ice to change directly from a solid to a vapor without passing through a liquid phase. Freeze Drying, also known as lyophilization, is a process that is used for sample preparation.
