  • 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.

  • End-Zone End Point Detection System-Set Up

    Know as soon as your samples reach dryness. Set up your End-Zone™ End Point Detection System to alert you when the primary drying phase is complete for up to 5 samples in 600ml or larger flasks. This video shows how to install and operate the system.
