Vacuum Instruments For Lyophilizers | What You Need To Know

Posted by Eric Beardslee on Jan 7, 2015 12:13:43 PM


Accurate, reliable vacuum readings during freeze drying processes is one of the bigger challenges faced by users of older lyophilizers, and an even greater challenge faced by those designing new systems.

Freeze drying, whether done on an industrial scale (e.g., prepared foods, coffee, pet products) or in laboratory/pharmaceutical facilities (e.g., chemical compounds, vaccines, tablets), is a process of controlled dehydration wherein system vacuum levels greatly influence not only product quality, but also the efficiency of the entire drying cycle.

Much of the drying profile hinges on proper integration of the vacuum instrument into the host drying system. 

Retrofitting old, multi-chamber, large-chamber or installing new systems all have different requirements. Selecting the right vacuum instrument for your project is imperative to proper integration. 

Learn more from Digivac’s lead vacuum engineer, Tom Bassi, as he provides a rundown on specific vacuum instruments commonly installed in freeze dryers.
