Why Choose AKGJ-12 Freeze Dryer
The AKGJ-12 delivers an optimal balance of capacity, precision, and usability. Its compact design, high vial throughput, and stable operating parameters make it an excellent choice for small-batch R&D, formulation trials, and laboratory lyophilization projects.
Principles of Freeze Drying
Freeze drying (lyophilization) is a dehydration process for temperature-sensitive materials. It involves three stages: freezing the sample, primary drying (sublimation) under vacuum to remove most water, and secondary drying (desorption) to remove residual moisture while preserving structure and bioactivity. For more details, see ScienceDirect Freeze Dryers. The AKGJ-12 precisely controls temperature and vacuum to ensure consistent, high-quality vial-based freeze drying.
