Overview

Discover the science behind pharmaceutical freeze drying in this educational animation. Freeze drying, or lyophilization, is the process of removing water from drug products to ensure long-term stability. Take a look inside the freeze dryer and see how the different components work together throughout each of the four stages of the freeze drying.

Objectives

Take a look inside the freeze dryer and see how the different components work together – including the product chamber, condenser, vacuum, refrigeration, and heating systems. Follow each stage of the process, from freezing to primary and secondary drying, and see how precise temperature and pressure control transform ice crystals directly into vapor. Witness the final steps as the dried product is sealed and prepared for use in healthcare.

After watching this video, you'll be able to:

  • Explain the process of freeze drying and its role in preserving drug products for long-term stability.
  • Identify the key components of a freeze dryer, including the product chamber, condenser, and systems for vacuum, refrigeration, and heating.
  • Describe the four stages of freeze drying, with emphasis on the roles of temperature, pressure, and time in each stage.
  • Outline the steps involved in the primary and secondary drying phases, including the concepts of sublimation and bound water removal.
