This seminar will give a thorough introduction into the Physics and Thermodynamics of Freeze-Drying. It comes with an additional overview about technical aspects to be considered and gives an overview about current technologies available on the market. It is created to introduce all people who are professionally linked to Freeze-Drying and might be of special interest for cycle developers (R&D), upscale & transfer specialists, project managers & engineers, process & site engineers, qualification & validation specialists. Open problem examination allows you to bring in a current problem linked to Freeze-Drying. The group will discuss and evaluate possible approaches for troubleshooting.

Who should attend?

This course is designed specifically for:

  • Cycle Developers (R&D)
  • Upscale & Transfer Specialists
  • Project Managers & Engineers
  • Process & Site Engineers
  • Qualification & Validation Specialists
  • Members of Parenteral Production Teams

Learning Objectives

Upon completion of this course participants will know the basic principles of all Freeze Drying aspects:
  • Physical / Thermodynamic Theory of Nucleation, Sublimation and Desorption
  • Technical & Technological Solutions to accomplish a standard process
  • Based on the prior theory, several hands-on-sessions provide practical knowledge to design a Freeze-Drying process
  • Basics of qualification of a freeze dryer


Georg Frinke, Bayer Pharma
Georg holds a degree in Engineering from UAS, Cologne, Germany. He is Process Engineer at Bayer Pharma and responsible for the technical operation of the parenteral facility. Previously, he worked as Process Engineer for Optima (Klee) and GEA Lyophil / Steris. Among others, he is specialized in the development of customized Freeze-Drying processes (particularly upscaling with PAT) and in the qualification (FAT, SAT, IQ, OQ, PQ) of pharmaceutical freeze dryers.
