Vacuum Freezing Dryer
  • Search Hot:979
  • Category: Product Scientific Instrument
  • Model:Vacuum Freezing Dryer
  • Instrument introduction
    Vacuum freeze-dryer: firstly freeze the water-containing material below the eutectic temperature to make the water solid ice, then under a higher vacuum, the ice is sublimated directly into water vapor, and then the water vapor condenser vapor condensation to obtain a dry product technology.
     
    Normal type: Suitable for freeze drying of bulk (liquid, pasty, solid) conventional materials.
    Gland type: not only suitable for freeze drying of bulk (liquid, pasty, solid) conventional substances, but also suitable for western Drying of forest bottled materials, lyophilized preparation, according to the need to separate the material in the vial, freeze-drying after the cover is well covered, after the end of drying, operate the capping device and move the cap tightly to achieve the vacuum state. Sealed, easy to long-term preservation.
