Lyophilization cycles consist of three phases: Freezing, primary drying, and secondary drying. Conditions in the dryer are varied through the cycle to ensure that the resulting product has the desired physical and chemical properties and that the required stability and sterility is achieved and maintained. During the freezing phase, the goal is to freeze the mobile water of the product. Significant supercooling may be encountered, so the product temperature may have to be much lower that the actual freezing point of the solution before freezing occurs.

Generating very large frozen particles due to the initial freezing process can cause the sedimentation rate to go way up causing a much longer cycle than effective design of the process can accomplish making the process more cost effective and higher quality.

Why should you Attend?: The fundamental principles and technology are coupled with practical aspects of lyophilization in the training program. Principles and concepts presented are later used to discuss real world practical applications. The long term training sessions include participants in development, operations, engineering, technical services, quality, validation, and regulatory affairs. Brief on-line training addresses critical aspects of freeze drying to ensure compliance, validation and minimization of patient risk based on the development of the product proven to have been during the clinical trials before the product was transferred into commercial scale operations.
