abstract: When considering the purchase of a freeze-dryer, the user must establish his own performance standards and particular requirements for the following reasons: 1. Large monetary investment required for the purchase, operation and maintenance of the equipment. 2. The expense and stability of the products to be freeze-dried. Some of the basic parameters that must be considered: 1. Product requirements, such as volumes, optimum temperature, and vacuum limits. 2. Facility restraints relating to the availability of space, and utilities. 3. Return on the capital investment (ROI) 4. Technical competence of operating and maintenance personnel. When the parameters are established, the buyer is prepared to purchase a freeze-dryer to best suit his needs. Precise cycle development, reliable hardware and personnel training, assure productivity and product quality.
