Lab Freeze Dryer

Introduction of Freeze Dryer

The freeze dryer (lyophilizer or freeze dryer) originated from the vacuum freeze-drying technology in the 1820s. It refers to a process in which solid materials are directly sublimated into a gaseous state under vacuum conditions without going through the liquid phase. During the freeze-drying process, the original chemical structure and morphology of the solute will not be destroyed. In addition, the biologically active material can still restore the conformation and biological function before freeze-drying after being re-dissolved. Compared with other drying methods, vacuum freeze-drying technology has incomparable advantages, so this technology is increasingly widely used in biology, medicine, food, environment, etc.

  • Features of Freeze Dryer
  • 1. Heat sensitive substances will not be denatured or inactivated.
