Gail's Story Changed the Way We Think About Lab Freeze Drying
When she visited Kelly at Labconco, Gail's struggle led to an epiphany that would change how laboratory freeze drying is done. With the creation of Lyo-Works OS, samples can now be monitored from anywhere. And with End-Zone™ End Point Detection, now FreeZone Freeze Dryers can even send you an alert when your samples are completely lyophilized.
