Freeze-drying microscope

The freeze-drying microscope uses a low-temperature stage to freeze the sample and observes the morphological changes of ice crystals and material structure in a vacuum environment. It is used to determine key parameters such as the eutectic point and collapse temperature of materials, guide the setting of freeze-drying processes, and monitor changes in material states during the freeze-drying of pharmaceuticals, food, and biological products.
Selection
When selecting, pay attention to the temperature control range, which should cover -50℃ to room temperature, with a cooling rate of no less than 10℃ per minute. The system should be equipped with a high-resolution camera and a long working distance objective lens. The vacuum system should maintain a level of 10-3 mbar and include video recording capabilities. Consider the compatibility of the sample stage size with glass slides, and ensure the software supports temperature curve recording and image analysis functions.
