Abstract
A cell culture vessel formed generally about an elongate axis and being provided with a neck and a removable closure member, and at a distal end thereof an end closure portion; said vessel being adapted for tissue culture growth and formed of a sterilizable plastics material, wherein the internal surface of the vessel is wettable for the attachment of cells; said vessel being characterized in that its cross-section in a direction perpendicular to said elongate axis is non-cylindrical whereby it cannot rotate smoothly by rolling on its surface(s).
Claims5
A cell culture vessel formed generally about an elongate axis and being provided with a neck and a removable closure member, and at a distal end thereof an end closure portion;
- said vessel being adapted for tissue culture growth and formed of a sterilizable plastics material, wherein the internal surface of the vessel is wettable for the attachment of cells;
- said vessel being characterized in that its cross-section in a direction perpendicular to said elongate axis is non-cylindrical whereby it cannot rotate smoothly by rolling on its surface(s);
- wherein the vessel further comprises a drainage channel which extends radially outwardly relative to the elongate axis of the vessel and has a point of maximum displacement adjacent to either or both ends of said vessel;
- wherein a major portion of the drainage channel is generally parallel to the elongate axis of the cell culture vessel and wherein a radially outwardly formed well is disposed adjacent at least one end portion of the vessel;
- and
- wherein the internal surface of the vessel is corrugated.
An elongate cell culture vessel having a hollow body portion formed of a sterilizable plastics material and shaped externally to resist rolling, a major portion of said body portion being formed with corrugations to present an increased surface area internally of said vessel for culture growth;
- the body portion being further formed with a drainage channel running longitudinally of said vessel, intersecting said corrugations and defining a drainage location for liquid in the vessel;
- the drainage channel extending outwardly of the remainder of the body portion at least in the vicinity of said drainage location, providing a key indicative of a desired operational orientation for the vessel.
A cell culture vessel formed generally about an elongate axis and being provided with a neck and a removable closure member, and at a distal end thereof an end closure portion;
- said vessel being adapted for tissue culture growth and formed of a sterilizable plastics material, wherein the internal surface of the vessel is wettable for the attachment of cells;
- said vessel being characterized in that its cross-section in a direction perpendicular to said elongate axis is non-cylindrical whereby it cannot rotate smoothly by rolling on its surface(s);
- wherein the vessel further comprises a drainage channel which extends radially outwardly relative to the elongate axis of the vessel and has a point of maximum displacement adjacent to either or both ends of said vessel;
- wherein a major portion of the drainage channel is generally parallel to the elongate axis of the cell culture vessel and wherein a radially outwardly formed well is disposed adjacent at least one end portion of the vessel;
- and
- wherein the shape of the cross-section of the vessel is selected from an oval, an egg-shape, a triangle, a square, a rectangle, a pentagon, a hexagon and generally a right cylinder but with a radially outwardly extending drainage channel thereon.
