Vessel for culturing cells

1. An apparatus for culturing cells, comprising:

a plurality of culture compartments, isolated from one another by one or more separator wails, at least two of said culture compartments being joined to a in fluid communication with a pooling compartment at one end of said culture compartments; wherein said apparatus is constructed and arranged such that:

in a first orientation of said apparatus, said pooling compartment is located below said culture compartments whereby liquid contents in said at least two culture compartments will flow into said pooling compartment to pool the liquid contents of said at least two culture compartments,

in a second orientation of said apparatus, said pooling compartment is located above said culture compartments whereby liquid contents in said pooling compartment will flow into said at least two culture compartments for splitting liquid contents of said pooling compartment into said at least two culture compartments, and

in said second orientation, cultures of cell units in each of said culture compartments may be exposed to differing culture conditions, in isolation, wherein said apparatus is in the form of a U-shaped vessel comprising first and second arms and an arcuate portion joining the first and second arms, wherein the bottom extends arcuately in said U-shape and the walls extend inwardly from said bottom in said first arm and arcuately in the curved portion of the vessel, such that the culture compartments are present in the first arm of the vessel and the pooling compartment exists in the second arm of the vessel.

2. An apparatus for culturing cells comprising two or more culture compartments and a pooling compartment, wherein:

said apparatus comprises a first end and a second end and a bottom extending from said first end to said second end, one or more walls projecting from said bottom and extending from said first end of the apparatus to positions intermediate the first and second ends to define said two or more culture compartments, each of said two or more culture compartments is being separated from the other culture compartments by said one or more walls, and each of said two or more culture compartments having a channel shape having an open end located intermediate said first and second ends of the apparatus;

each of said two or more culture compartments comprises a port for the addition or removal of medium; and

the pooling compartment is positioned intermediate said second end of the apparatus and said open ends of said channel-shaped culture compartments and communicates with said open ends of said two or more culture compartments, wherein said apparatus is in the form of a U-shaped vessel comprising first and second arms and an arcuate portion joining the first and second arms, wherein the bottom extends arcuately in said U-shape and the walls extend inwardly from said bottom in said first arm and arcuately in the curved portion of the vessel, such that the culture compartments are present in the first arm of the vessel and the pooling compartment exists in the second arm of the vessel.

3. An apparatus according to claim 1 , wherein the culture compartments are arranged substantially parallel with each other in the vessel.

4. An apparatus according to claim 2 or claim 1 , which is constructed from a material selected from the group consisting of polyethylene, polypropylene, polyvinylchloride, polycarbonate, polystyrene, polyester, nylon, aramid polymers and a metal, or combinations thereof.

5. An apparatus according to claim 2 or claim 1 , which is at least partly optically transparent.

6. An apparatus according to claim 2 or claim 1 , comprising a dust shield or lid at least partially covering some or all of the compartments.

7. A kit comprising an apparatus according to claim 2 or claim 1 , one or more microcarriers and optionally one or more tags.

8. A kit according to claim 7 , wherein said tags are used for labelling microcarriers and/or for labelling cells.

9. A kit according to claim 7 , further comprising cells and/or cell culture or washing media.

10. An apparatus according to claim 2 , wherein the port present in each culture compartment comprises a filter to allow removal of any one or more of culture medium, and cells which have become dissociated from cell units, whilst retaining cell units within the compartment.

11. An apparatus according to claim 2 , which comprises, in addition to said ports, one or more routes for the addition or removal of medium.
