Reasons for choosing SJIA-5FE pilot freeze dryer
A simple experimental freeze dryer such as the SJIA-10N/12N/18N series consists of a vacuum pump, drying chamber, chiller and cold trap. Such freeze dryers are typically pre-frozen in other cryocontainers and a small amount can be carried out in a cold trap. The drying chamber is a transparent bell jar with a built-in stainless steel sample rack. The freeze dryer has a simple structure and a single control function, and is generally suitable for lyophilization of simple water-soluble samples. Process: Pre-freezing is done outside the dry room (either external or cold trap) and then moved into the drying chamber partition before the vacuum pump is turned on. Disadvantages: Separation of pre-freezing and drying. In the dry phase, the refrigeration will no longer continue to provide samples, and there is no controllable heat supply for sublimation of the material. The temperature of the material will rise significantly with the introduction of external heat. If the material temperature is higher than its glass transition temperature or eutectic point temperature, it will cause the material to collapse or melt, which will have a great impact on the quality of the freeze-dried product. In order to solve this problem, Shuangjia specially launched the SJIA-5FE freeze dryer for small freeze dryers. Temperature controlled shelves are provided, pre-frozen and dry in one. The pre-freezing temperature can be controlled to reach -50 °C; The sublimation shelf temperature can be controlled to precisely control the heat required for sublimation. Sublimation stage separator temperature can be controlled from -40 °C to -50 °C (higher temperature can be customized). Many materials, such as thermosensitive proteins, need to be controlled to sublimate between -20 °C and -30 °C. The 10N series cannot control heat and temperature, while the 5FE provides precise heat. The 5FE pilot freeze dryer provides process setting functions: Program control can be set, automatic operation can be realized, process data can be exported, and it can directly correspond to production type freeze dryer. Provides extremely important data for lyophilization testing as a reference.
