  • Chromatographic column and valve with movable valve sleeve
    Patent number: 6117317
    Abstract: A chromatography column having at least one central slurry valve positioned at either the top cell assembly and/or the bottom cell assembly. The central slurry valves have a pneumatically actuated valve sleeve which can be shifted to create three different flow configurations. One flow configuration allows for the simultaneous cleaning in place of the flow path used to charge the column with chromatography media and the separate processing of fluid through the chromatography media. The other flow configurations permit the reslurrying and removal of chromatography media from the column, and the subsequent repacking of the column with fresh chromatography media without disassembling the column.
