Abstract
Official abstract text for this publication.
A plate apparatus for use in countercurrent chromatography is disclosed which comprises a disk shaped tube support ( 60 ) having a tube support pattern form in an upper surface ( 63 ) of the support and configured to accommodate at least one layer of fluid flow tubing ( 70 ), wherein the pattern comprises at least one spiral groove ( 62 ) and at least one return path ( 72 ).
First claim
Opening claim text (preview).
What is claimed is: 1. A tube support for use in a countercurrent chromatography apparatus, comprising: first and second opposed surfaces; a plurality of interleaved spiral grooves forming a continuous channel in the first surface and configured to accommodate at least one layer of fluid flow tubing, wherein the spiral grooves have an inlet space and an outlet space formed on the first surface; at least one planar return path formed in the same surface as the plurality of spir…
