Abstract

A chromatography column having a longitudinal axis and comprising a column wall with a first end and a second end, a first end plate assembly removably connectable to said first end of the column wall, a second end plate assembly removably connectable to said second end of the column wall, wherein said first end plate assembly, said column wall and said second end plate assembly are arranged along the longitudinal axis of the column wherein the column wall, and/or first end plate assembly and/or second end plate assembly is/are rotatable about an axis of rotation wherein said axis of rotation is parallel to the longitudinal axis of said column and positioned outside the column.

Claims (15)

1. A chromatography column, having a longitudinal axis, comprising:

a column wall with an upper first end and a lower second end, a first end plate assembly removably connectable to said first end of the column wall, wherein the column wall is supported by a plurality of arms;

the plurality of arms is supported by a plurality of legs;

a second end plate assembly removably connectable to said second end of the column wall, wherein said first end plate assembly;

said column wall and said second end plate assembly are arranged along the longitudinal axis of the column wall; and

further wherein said column wall is configured to rotate approximately 180 degree about a leg of the plurality of legs out from between the first and second plate assemblies wherein said approximate 180 degree rotatable axis of rotation is parallel to the leg of the plurality of legs and positioned outside of the plurality of legs out from between the first and second plate assemblies.

2. The column of claim 1 , further comprising a movable adapter, movable along the longitudinal axis of said column from a position inside said column to a position outside said column.

3. The column of claim 2 , wherein said movable adapter is provided with means for releasably locking it to the column wall.

4. The column of claim 1 , farther comprising movable adapter lifting means.

5. The column of claim 1 , further comprising lifting means for first end plate assembly, adapted for lifting said first end plate assembly above said column wall.

6. A chromatography column, having a longitudinal axis, comprising:

a column wall with a upper first end and a lower second end, a movable adapter insertable into said first end of the column wall, wherein the column wall is supported by a plurality of arms;

the plurality of arms is supported by a plurality of legs;

a second end plate assembly removably connectable to said second end of the column wall, wherein said movable adapter, said column wall and said second end plate assembly are arranged along the longitudinal axis of the column wall; and

further wherein said column wall is configured to rotate approximately 180 degree about a leg of the plurality of legs out from between the first and second plate assemblies wherein said approximate 180 degree rotatable axis of rotation is parallel to the leg of the plurality of legs and positioned outside of the plurality of legs out from between the first and second plate assemblies.
