Vacuum Pumps for Freeze Dryers
Lyophilization removes solvent from a sample using vacuum-induced sublimation. Chemical resistance requirements for your freeze dryer vacuum pump depend upon the aggressiveness of your solvent. In all cases, a high gas flow is required at a low operating vacuum level. Collector temperatures and cleanliness must be considered and maintained to protect your pump.
