• 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.
