Nail, Wegiel and Sacha of Baxter. Representatives from Mettler-Toledo and McCrone were also on hand to instruct and provide hands-on training with DSC and FD microscopy. The class was divided into teams, each with a project to work on over the 2 ½ days, with each team presenting their findings and challenges at the closing program. On Wednesday afternoon, 20 industry members from Indiana SMEs and LyoHUB members arrived for hands-on training in the LyoHUB demonstration facility followed by a day of classes on Lyocalculating, CFD, for industry as well as all of the students from the Lyo101 course. The keynote speaker for Thursday was Mike Pikal of the University of Connecticut, “Modeling in Freeze-Drying: Past, Current State and Future Perspectives”.

Methodology of Lyophilizers Characterization to Enable Modeling of Process Parameters During Cycle Scale Up Webinar
Date & Time: 6/21/2016 10:00 AM - 3:00 PM ET, Presenter(s): Dr. Serguei Tchessalov
- Session 1: 6/21/2016 10:00 AM - 11:00 AM ET
- Session 2: 6/21/2016 2:00 PM - 3:00 PM ET
Abstract:
Factory acceptance tests (FAT) are normally performed by manufacturer on “empty and dry” lyophilizers. Sometimes, manufacturers also perform “sublimation tests” to ensure that the condenser is capable of capturing the sufficient amount of water, specified by the user. These tests, however, might not generate enough meaningful data to enable a successful lyophilization process scale up. Drug product manufacturers often need information on heat transfer coefficients for the containers of use as well as information on capability of the dryer to maintain pressure set points at different loads.
In this presentation, the methodology of measurement of vial heat transfer coefficient (Kv) and minimum controllable pressure as a function of sublimation rate (Pmin) will be described. Kv and Pmin are key inputs in primary drying models, application of which to process design and scale up will be discussed and demonstrated.
