Abstract

Disclosed is a chromatography column cylinder () formed from a polymer composite comprising an outer layer () and inner layer () intended to be in direct contact with the intended contents of the cylinder in a volume (), wherein the outer layer supports the inner layer, for example when there is negative pressure in the volume (). In one embodiment, one of said layers is molded directly onto a surface of the other layer such that there is no gap between the two layers. Disclosed also is a method for forming a chromatography column cylinder.
