Chemical Resistance of Freeze
Dryer Components
The FreeZone Freeze Dry System 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 a number of different materials, some of which may
be attacked and degraded by certain chemicals. The degree of
degradation is dependent on the concentration and exposure
duration. Some of the major components of the FreeZone Freeze
Dry System that are susceptible to degradation are as follows:
Acids Buffers Solvents
