Lyostat 4 Freeze Drying Microscope

Every freeze-drying formulation has a critical temperature, below which it should be cooled for complete solidification and maintained below during primary drying in order to prevent processing defects. The Lyostat freeze drying microscope system allows observation of the sample structure during drying and heating so that the exact point of collapse can be determined. Once analysis has been carried out a cycle can be developed that is safe, robust, and cost efficient.
