Improved spiral tube assembly for high-speed counter-current chromatography [PDF]
Journal of Chromatography A, 2009 The original spiral tube support (STS) assembly is improved by changing the shape of the tubing, with 1-cm presses perpendicularly along the length. This modification interrupts the laminar flow of the mobile phase. The tubing in the four return grooves to the center of the rotor is flattened by a specially made pressing tool to increase the number of ...
