Manifold Freeze Dryers An Overview of Their Use ...

2017-8-7 · The vacuum pump for most manifold freeze dryers is a two stage rotary vane oil sealed vacuum pump. The vacuum pumps sole purpose during most of the freeze drying process is to remove non-condensable vapors (nitrogen, oxygen, carbon dioxide et al) from the freeze dryer. By removing the non-condensable gasses in the system the vacuum pump essentially helps to create the environment for sublimation (ice to vapor without going through the liquid phase) to occur. Because all freeze dryers are have leaks (virtual leaks -- outgassing from stainless steel (yes it may outgas), gaskets, acrylics et al and real -- little pinhole leaks of various configurations and locations within the system, such at the vacuum tube hook up between the condenser and the vacuum pump) the vacuum pump is operated continuously throughout the freeze drying cycle. Theoretically IF the freeze dryer were totally and completely leak free, once the vacuum pump
