Translation of the original operating manual
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
• The product must not damage the material of the components of the
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.
NOTE
The additional information concerning special products in the following
chapters must be absolutely observed (see chapter 1.2.1 - "Freeze-drying
of solvent-containing products (non-aqueous media)" and chapter 1.2.1 -
"Freeze-drying of solvent-containing products (non-aqueous media)")!

1.2.1
Freeze-drying of solvent-containing products (non-aqueous media)
With regards of corrosion resistance, the use of some organic solvents in
aqueous solutions with low concentrations is acceptable.
A freeze-dryer is designed to be chemically resistant to most compounds
that are commonly used in freeze-drying processes. However, by
necessity, the freeze-dryer is comprised of several different materials,
some of which may be attacked and degraded by certain chemicals.
The methods of fabrication and/or conditions of exposure of an acrylic door,
as well as the way the chemicals are applied, can influence the results.
Some of these factors are listed below:
• Fabrication: Stress generated while sawing, sanding, machining,
drilling, polishing, and/or forming.
• Exposure: Length of exposure, stresses induced during the life of the
product due to various loads, changes in temperature etc.
• Application of chemicals: by contact, rubbing, wiping, spraying etc.
