  • Multicartridge chromatography cartridge housing
    Patent number: 4604198
    Abstract: A multicartridge chromatography cartridge housing for use in supporting several chromatography cartridges in a parallel array is disclosed. A number of elongated cylindrical cartridge holders extend between a lower support plate and an upper support plate. Each such cartridge holder receives a chromatography cartridge which is held within the holder by suitable end caps and tie rods. Several truss rods serve to space the support plates from each other and to support the housing assembly. Fluid flow manifolds are secured to the lower and upper support plates and serve to distribute the fluid to, and consolidate the fluid received from the cartridges within the individual holders. The multicartridge chromatography cartridge housing in accordance with the present invention handles high fluid flow volumes with a small pressure drop and with a minimum hold up volume.
