Translation of the original operating manual
All of the process steps that are necessary for freeze-drying as well as any
necessary auxiliary processes (venting, defrosting, draining of media, leak
tests) 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).
The intended use also includes:
• Observation of all of the notes and instructions that are included in the
operating manual (see chapter 1.2 - "Further applicable documents")
• Compliance with the inspection and maintenance instructions (see
chapter 8 - "Maintenance and service").
Exclusion of liability
Any use of the freeze-dryer other than the one described here or any use
going beyond this description is regarded as improper use. Martin Christ
Gefriertrocknungsanlagen GmbH cannot be held liable for any damage
resulting from such improper use.
Requirements concerning the products used in the freeze-dryer

freeze-dryer or affect its mechanical strength.
• A reaction of the product following the supply of high amounts of energy
during the freeze-drying process must be excluded.
• The product must not be explosive or highly flammable since certain
components of the freeze-dryer are a potential source of ignition.
