Freeze Drying PAT using Heat Flux Measurement

Just in case you missed our webinar “Freeze Drying PAT using Heat Flux Measurement”, it is now available to view online.

A freeze drying recipe will be analyzed and then improved using Heat Flux measurement and Control. Heat flux measurements provide critical process information for every step of the freeze drying process, including: freezing, primary drying and secondary drying. By measuring heat flux in-process process parameters such as % of product frozen by nucleation, crystal growth rates post-nucleation(Controlled and UnControlled), end of freezing, thermal conductivity of the vial (Kv), product resistance (Rp), mass-flow, shelf surface temperature and product temperature can be measured. Additionally, a design space can be developed in a single run.
