The oil in the vacuum pump should be checked often. It must be changed
if it is cloudy, shows particles or is discolored. The useful life of vacuum
pump oil can be extended if the vacuum pump is operated for an extended
period of time after a freeze dry run. This allows contaminants to be
purged from the hot oil. This must be done with the inlet to the pump
blocked off to prevent air from free flowing through the pump. If the
pump is operated at an elevated vacuum level (> 10mBar), oil may be
expelled from the pump and damage could occur.
Another way to extend the life of the vacuum pump is to install an optional
secondary trap in the line between the freeze dryer and the vacuum pump.

vacuum pump must be vented to or operated inside a fume hood.
Hazardous materials such as strong acids or bases, radioactive
substances and volatile organics must be handled carefully and promptly
cleaned up if spilled. If a sample is spilled in the collector chamber it
must immediately be cleaned up.

equipment may be governed by various Federal, State or local
regulations. All users of this equipment are urged to become familiar
