End cell for chromatography column.

摘要

An end cell for a chromatography column has a moulded plastics structure and an integral screen formed of a woven mesh (12) of fibres with a peripheral ring (22) of the same plastic material as used for the end cell (10 or 20). The peripheral ring of the same plastics material is injection moulded to the perimeter of the mesh, said ring being secured to the end cell in a leak-proof manner, preferably by vibration welding.
