1.3
Intended use
The freeze-dryer has been exclusively designed for the freeze-drying of
solid or liquid products in ampoules, vials or dishes. It is, therefore, solely
intended for this application.
All of the process steps that are necessary for freeze-drying can be
performed in the system:
• freezing of the products with time and temperature setpoints that can be
preset as desired
• main drying of the products with time, temperature and pressure
setpoints (sublimation) that can be preset as desired
• secondary drying of the products with time and temperature setpoints
that can be preset as desired, and with a high final vacuum for
eliminating any water that is bound by capillary or molecular effects
(desorption)
The freeze-dryer is suitable for freeze-drying solid substances and aqueous
solutions (e.g. bacteria and virus cultures, blood plasma, serum fractions,
antibodies, sera, vaccines and pharmaceutical products such as
chloramphenicol, streptomycin, vitamins, ferments and plant extracts for
biochemical tests).
