A slurry chamber is fastened to and held in coaxial alignment with a chromatography column by a V-band. One end of the column has an end cap and frit. A slurry of fluid and chromatographic media is placed in the column and chamber. A piston is forced through the chamber and into the column by a hydraulic ram to expel the fluid and form a media bed in the column. The slurry chamber is removed, and a split end cap is fastened to the column. A threaded recess in the split end cap receives a split, threaded collet. The collet is tightened until it pushes against the piston with the same force as the ram, at which point the ram is released and the column removed for use.

Methods and systems for chromatography are disclosed that employ a flexible container configured to fit within a support structure and adapted to receive a filtration or absorptive medium. The flexible container can include at least one inlet, at least one outlet, and a separation barrier peripherally sealed within the container to separate the container into a resin containing portion and a drainage portion. The barrier can be configured to exclude the resin material from the drainage portion while allowing fluids to pass therethrough. The disposable chromatography system can further include one or more agitators disposed within the flexible container and adjustably configured to be raised or lowered in the flexible container. When the agitator is in the raised position, the resin packing material can operate in a settled, packed-bed configuration. Alternatively, the agitator in the lowered position permits the chromatography resin packing material to operate in a mixed, slurry configuration.

A method and a system for transferring a slurry of a separation resin, from at least one first container to a second container, said method comprising the steps of: connecting the at least one first container to the second container by a transferring connection; providing a degree of vacuum to the second container by a vacuum production device connected to the second container; allowing the vacuum in the second container to affect the content in the at least one first container through the transferring connection such that the slurry initially provided in the at least one first container is transferred to the second container through the transferring connection.

A method and a system and a container system for transferring separation resin from at least one first container (3; 3; 3a, 3b; 3a, 3b, 3c, 3d) to a second container (5; 5), wherein said first container is a deformable, single-use separation resin storage container, said method comprising the steps of:preparing (S1) the at least one first container by providing a deformable, single-use container comprising an outlet port (4) with a predefined volume of separation resin in a storage solution;fluidizing (S3) the separation resin in the at least one first container to provide a resin slurry, said fluidizing being performed by mechanical interaction to the first container from an outside of the first container to provide a deformation of said first container;fluidically connecting (S5) the outlet port (4) of the at least one first container to an inlet port (103) of the second container;transferring (S7) separation resin from the at least one first container to the second container by generating a pressure difference between an interior of the second container and an interior of the first container where the pressure is lower in the second container.

A method for packing a media bed in a column (3). According to the invention the method comprises the steps of: providing data to a control unit (15) connected to the column (3), said data comprising at least a measured slurry concentration, a target bed height, a target packing factor or compression factor and minimum and maximum acceptable values for at least one of target bed height and target packing or compression factor; forcing a movable adapter (9) along a longitudinal axis of the column (3) in order to pack the media; detecting when the media bed is consolidated; the control unit (15) processing the provided data and the information about the consolidated bed height in order to present to the user acceptable bed heights, if there are any, giving acceptable packing or compression factors.

The present invention relates to axial flow chromatography columns, methods for separating one or more analytes in a liquid by the use of such columns, and systems employing such columns. The column comprises a first port and a second port, the first port and said second port being at essentially the same level or elevation above the level of the bed space on the chromatography column.

A column filling apparatus mainly includes a tank, a stirrer being an agitator, a pump, a resin bottle, first to eleventh pipes, first to fourth valves composed of three-way valves, and fifth and sixth valves composed of two-way valves. A suction port is mounted on a leading end of the fifth pipe, and the suction port is inserted into an inner part from a top opening of the resin bottle. The other end of the fifth pipe is connected to the first valve. The first valve is connected to the first pipe, the second pipe, and the fifth pipe, and connects or disconnects these pipes to or from each other. An end of the first pipe is mounted near a bottom of the tank, and is opened near an inner bottom surface of the tank.

Methods and systems for chromatography are disclosed that employ a flexible container configured to fit within a support structure and adapted to receive a filtration or absorptive medium, such as a chromatography resin. The flexible container can include at least one inlet, at least one outlet, and a separation barrier peripherally sealed within the container to separate the container into a resin containing portion and a drainage portion. The barrier can be configured to exclude the resin material from the drainage portion during use while allowing fluids to pass therethrough. The disposable chromatography system can further include one or more agitators disposed within the flexible container and adjustably configured to be raised or lowered in the flexible container. When the agitator is in the raised position, the resin packing material can operate in a settled, packed-bed configuration. Alternatively, the agitator in the lowered position permits the chromatography resin packing material to operate in a mixed, slurry configuration.

Systems include a chromatography column tube having an inlet and outlet and port assembly arranged in a wall of the column tube between flow distributors that together form a chamber within the tube that is filled with packing medium are described. The port assembly facilitates the removal of resin from the pre-packed column and the port assembly does not affect fluid flow in the normal use of the column for chromatographic separation or ability to maintain sanitary conditions within the column. Also described are methods that include attaching tubing to a pump and to a column inlet and a column outlet, opening the port assembly, attaching tubing to the port assembly and to a second reservoir, and pumping aqueous solution from a reservoir into the chamber and out through the port assembly into the second reservoir, thereby removing packing medium from the column along with the flowing aqueous solution.
