C – Moderate degradation; Limited use.
D – Severe degradation; infrequent use recommended; immediate
thorough cleaning required.
 Most common compounds used in freeze drying processes, if allowed to enter
the vacuum pump, will degrade the oil and cause damage to the vacuum pump.
 Sugars and proteins typically will have minimal negative effect on any of the
materials of construction.
When using compounds in the Freeze Dryer that are hostile to the materials of
construction, it is imperative the equipment is thoroughly cleaned after use.
