The preservation of biological, pharmaceutical, and food samples is a crucial aspect of modern laboratories. In this context, lyophilizers play an essential role by enabling efficient water removal without compromising the integrity of the samples. Lyophilization, also known as freeze-drying, offers a safer and more effective alternative than other preservation methods. This article explores the features, applications, and advantages of lyophilizers, with a particular focus on Kalstein models, a well-known brand in the laboratory equipment market.
Lyophilizers
Lyophilizers are devices designed to dehydrate sensitive products through a sublimation process, where water moves directly from a solid state (ice) to a gaseous state (vapor) without passing through the liquid phase. This process is carried out under vacuum and controlled temperature conditions, allowing the preservation of the physical and chemical properties of the samples. Lyophilization is especially useful for biological samples, pharmaceutical products, and foods that require maintaining their biochemical activity or cellular structure intact.
In laboratories, lyophilizers are used to preserve samples such as proteins, nucleic acids, vaccines, biological products, and materials sensitive to moisture. Additionally, they are widely employed in the food and pharmaceutical industries to produce dehydrated products that can be stored long-term without losing their nutritional or medicinal value.
