The freeze dryer, also known as a lyophilizer, is an instrument that executes the process of lyophilization in laboratories and small production environments. It is mainly used for freeze-drying of heat-sensitive or easily destructive substances such as biological products, pharmaceutical intermediates, and foodstuffs.
In a freeze dryer, the materials are frozen first and then the frozen water in the material directly turns into vapor in a vacuum environment, thereby removing the ice by sublimation. This type of drying under low temperatures and vacuum conditions can effectively retain the structural and functional properties of the materials.
Compared with conventional hot air drying, freeze dryers have significant advantages. The drying process in the lyophilizer does not adversely affect the biological activity of the substance and also prevents heat-sensitive substances from being damaged or denatured due to high temperatures. In addition, freeze dryers offer high drying efficiencies and consistent, with reliable product quality, making them suitable for drying small batches of highly valuable laboratory samples.
Amerigo Scientific provides a range of freeze dryers designed to deliver consistent and high-quality results for our customers, making even the most challenging samples easy to handle.
