Abstract
A flow-through apparatus for two-phase countercurrent chromatography consisting of a multi-layer helically coiled column carried on a flanged reel mounted on a frame revolving on a first axis. The reel rotates on a second axis parallel to and spaced from the first axis, at the same angular velocity and in the same direction as the frame to prevent twisting of its inlet and outlet flow tubes, which extend through an axial passage in a shaft portion of the reel. The reel has opposite shaft portions which are journalled in detachable opposite bearing blocks carried by the frame. The bearing blocks have a plurality of sets of bearings spaced to define different spaced positions of the second axis relative to the first axis, enabling adjustment of the .beta. value for the system as required. A counterweight is detachably mounted on the frame opposite the multi-layer coiled column by means of detachable supporting blocks, enabling the counterweight to be readily replaced as required by the .beta. adjustment.
