Abstract

A chromatography column having an end arrangement including an end plate having a fluid opening and a filter extending over an internal surface of the end plate to define a fluid flow zone between them into which the fluid flow opens is disclosed. There is a liner between the end plate's internal surface and the filter layer. The liner has a surface relief pattern to space the filter layer from the end plate and maintain the fluid flow zone across the filter.
