Low temperature and very low atmospheric pressure are preserved. Freons are used as refrigerant. Development of ice crystals happens. The speed of ice crystallization define the freezing process and effectiveness of Key drying.

But as the two stages are so various in processing phrases, when And exactly how the alter should arise is of critical worth to your success of the process and reducing cycle time.

This evaluate focuses on the lyophilization process, style of freeze dryer, purpose of excipients in lyophilation process, final decision of choosing theexcipients, relevance of cake framework really helps to establish stable lyophilsized drug merchandise for prolonged-time period usage and applications of lyophILization know-how.
