Overview:
Jeff Schwegman Founder and CEO, AB BioTechnologies LLC
This webinar will cover the process and benefits of using an empirical approach to design an optimized lyophilization cycle. Optimized lyophilization cycle design can be an extremely difficult and daunting task for the scientist that is unskilled or under skilled in the process. This is becoming even more prevalent as many of the molecules coming out of discovery are more complex, unstable, and require a very specific, multi component formulation to impart not only good chemical stability and physical stability to the active ingredient, but also good physical stability to the dried solids themselves.
Areas Covered in the Session: l
Thermal characterization including DSC and FDM
l
Understanding the effects of working with crystalline vs. amorphous components The problem with working with a metastable glassy system and the use of annealing to correct this problem Determining optimal shelf temperatures for the freezing step Determining optimal shelf temperatures and chamber pressures for the primary drying step Determining optimal shelf temperatures and chamber pressures for the secondary drying step Characterization of the finished lyophilized product
