Introduction to Bell Jar Freeze Dryer
A bell jar freeze dryer is a crucial piece of equipment in the field of scientific research, pharmaceutical manufacturing, food processing, and other industries. It operates on the principle of sublimation, where water in a frozen sample is directly converted from the solid state (ice) to the gaseous state (vapor) under low - pressure conditions. This process helps to preserve the structure, composition, and biological activity of the sample, making it suitable for long - term storage and subsequent analysis. The bell - jar design provides a visible and accessible chamber for sample placement and observation during the freeze - drying process.
