 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.
