Packing system and method for chromatography columns
View Patent ↗A method for providing an aseptic chromatography column includes the steps of pre-sterilizing an empty chromatography column, pre-sterilizing a chromatography medium, introducing the pre-sterilized chromatography medium into the pre-sterilized chromatography column using aseptic equipment, thus providing an aseptic chromatography column comprising chromatography medium.
1. A method for providing an aseptic chromatography column, said method comprising:
providing an empty chromatography column having a housing including sidewalls and including a first end unit forming an external surface of the chromatography column and extending above the sidewalls and including a valve for admitting chromatography medium in a slurry or suspension and a filter extending across an area of a bed space of the chromatography column along an inner surface of the first end unit;
pre-sterilizing the chromatography column;
providing chromatography medium through the valve into a bed space within the chromatography column;
pre-sterilizing the chromatography medium;
adjusting the height of the bed space within the chromatography column by controllably adjusting the first end unit and the filter thereon by an external drive having a platform attached to the first end unit, to a specific position at a distance greater than that of a target bed height wherein the first end unit is spaced a predetermined distance above the sidewalls of the housing;
introducing the chromatography medium as a suspension or slurry into the chromatography column using aseptic equipment; and
compressing a bed of the chromatography medium within the chromatography column once the flow of suspension or slurry has stopped by performing axial movement of the first end unit and the filter thereon in a downward direction until the first end unit rests on the sidewalls of the housing.
2. The method according to claim 1 , wherein the step for pre-sterilizing of the chromatography column and the step of pre-sterilizing of the chromatography medium include at least one of the sterilization methods of: heat sterilization by autoclaving or steaming (in place); chemical sterilization; gamma irradiation; and eBeam irradiation.
3. The method according to claim 2 , wherein the sterilization method used for the pre-sterilizing of the chromatography column is different from the sterilization method used for the pre-sterilizing of the chromatography medium.
4. The method according to claim 2 , wherein the sterilization method of the chromatography column and the sterilization method of the chromatography medium are the same whereby the intensity protocol for performing those sterilization methods are different.
