Poster Presentation! Jason B. Angstadt, Scientist III; Project Director, Lyophilization Technology, Inc. will be presenting his co-authored poster entitled "Inert Gas Bleed Valve Location and the Impact on Lyophilization Chamber Temperature" on March 25th thru March 27th, 2024, in Long Beach, California for the PDA Annual Meeting!

Abstract - Nitrogen gas is bled into the lyophilization chamber to control the chamber pressure during primary and secondary drying. The location of the Nitrogen gas bleed valve is an often overlooked variable when transferring a cycle from one lyophilizer to another. The focus of these studies will be how the location of the gas bleed valve effects the primary drying segment of the lyophilization cycle. The location of the gas bleed valve was varied during these studies and the air temperature at different locations on the shelf and chamber was monitored during primary drying. The air temperature during primary drying was compared by shelf and shelf location to investigate the effects of varying the location of the Nitrogen gas bleed valve.

Copies of this presentation will be available after PDA Annual Meeting 2024
