Abstract: The present invention describes a device for distributing incoming fluid or for collecting fluid being discharged from a column forming part of an assembly of N columns in series intended to be used in a simulated moving bed separation process. The present device can be used to very substantially reduce the non-selective volumes at each column, while at the same time providing the flow with good synchronicity.
