Apparatus for cellular culture

Claim 2

Apparatus for effecting cellular culture which comprises: (a) at least one culture vessel; (b) a plurality of discrete tubes having an opening at each end thereof disposed inside said culture vessel parallel and equi-distant to one another; (c) means to introduce a suspension of cells in said culture vessel; (d) means creating an aerobic condition in said culture vessel; and (e) means to cause rotation of said culture vessel and of said tubes about an axis parallel to the longitudinal axis of said tubes.

Claim 3

Apparatus according to claim 1 wherein said culture vessel is elongated and cylindrical.

Claim 4

Apparatus according to claim 2 wherein said culture vessel is tapered at both ends, each of said ends being formed with an opening adapted to introduce or remove liquid from said culture vessel.

Claim 5

Apparatus according to claim 3, wherein the length of said tubes in said culture vessel varies depending on the space which is available in said culture vessel.

Claim 6

Apparatus according to claim 4, wherein the inner diameter of each said tube is about 5 to 7 mm and the outer diameter of said tube is about 7 to 9 mm.

Claim 7

Apparatus according to claim 5, wherein the closest distance between each of said tubes is about 1 mm.

Claim 8

Apparatus according to claim 5, wherein said closest distance is obtained by mounting inert rings around said tubes.

Claim 9

Apparatus according to claim 7, which comprises means to proportion the total volume inside the tubes and the total volume outside the tubes respectively to the total surfaces inside the tubes and the total surfaces outside the tubes.

Claim 10

Apparatus according to claim 1, wherein said culture vessel and said tubes are made of borosilicate glass.

Claim 11

Apparatus according to claim 1, wherein said culture vessel and said tubes are made of inert plastic allowing anchorage of said cells.

Claim 12

Apparatus according to claim 1 further comprising a reservoir to contain a liquid medium in contact with a gaseous phase within said reservoir, duct means connecting said culture vessel and said reservoir, and a pump associated with said duct means enabling said liquid medium to circulate through said duct means and said culture vessel.

Claim 13

Apparatus according to claim 2 wherein said means to cause rotation comprises motorized rollers bearing against said culture vessel.

Claim 14

Apparatus according to claim 1 wherein said tubes occupy substantially the entire interior space of said culture vessel.

Claim 15

Apparatus for effecting cellular culture comprising at least one elongated cylindrical culture vessel having at least one end tapered toward an opening at that end of the culture vessel, a plurality of discrete tubes having an opening at each end thereof occupying substantially the entire interior space of said culture vessel, said tubes being located parallel to each other and parallel to the major wall of said culture vessel, said tubes being spaced from said major wall and being spaced from each other at an equal distance by inert spacing means, means to introduce a suspension of cells into said culture vessel through an opening at an end of said culture vessel, means creating an aerobic condition within said culture vessel, and means for rotating said culture vessel and tubes about an axis parallel to the longitudinal axis of said tubes.

Claim 16

Apparatus for effecting cellular culture comprising at least one elongated cylindrical culture vessel having at least one end tapered toward an opening at that end of the culture vessel, a plurality of discrete tubes having an opening at each end thereof occupying substantially the entire interior space of said culture vessel, said tubes being located parallel to each other and parallel to the major wall of said culture vessel, said tubes being spaced from said major wall and being spaced from each other at an equal distance by inert spacing means, means to introduce a suspension of cells into said culture vessel through an opening at an end of said culture vessel, means creating an aerobic condition within said culture vessel, and means for rotating said culture vessel and tubes about an axis parallel to the longitudinal axis of said tubes.
