Abstract:
A resin support apparatus for a chromatography column comprising:a stainless steel cylinder having an outer diameter and an inner diameter, the outer diameter being greater than a height of the stainless steel cylinder, the cylinder defining a groove in an exterior wall of the stainless steel cylinder, the groove being substantially parallel to an upper and a lower rim of the stainless steel cylinder; an â€œOâ€ -ring positioned within the groove, the â€œOâ€ -ring having an outer diameter greater than the outer diameter of the stainless steel cylinder; and, a stainless steel mesh welded to an upper surface of the stainless steel cylinder and covering an opening defined by the stainless steel cylinder; wherein, when said stainless steel cylinder is placed within a receiving surface formed on an interior surface of a volumetric cylinder, the â€œOâ€ -ring provides a fluid tight seal between the stainless steel cylinder and the inner wall of the volumetric cylinder, the stainless steel mesh providing a support platform adapted for receiving a supply of a chromatography matrix.
