Abstract
A high speed countercurrent centrifuge is designed so that the chromatographic column used therewith may be readily replaced. A shaft for rotating a chromatographic column includes a column holder plate fixed therearound. The column holder plate has upwardly extending pins which engage the corresponding holes on the bottom flange of a spool about which a chromatographic column is wrapped, fixing the orientation of the spool relative to the column holder plate. Also a multi-layer chromatographic column is constructed to be used in the centrifuge. Multiple layers of tubing are wrapped around the above-described spool. The inlet and outlet ends of this tubing terminate in tubing adaptors mounted on an outer surface of a flange to permit quick connection of the column to the flow tubes of the centrifuge apparatus.
