Abstract
A bioreactor, in particular for a microgravity, comprising at least one cell culture chamber, an oxygen supply and an agitator for a cell culture. In particular, the chamber includes two housing elements (1, 2) having a first (1', 9) and a second (2', 9') wall region, as well as a first (3) and a second (4) separating element extending from respectively the first (1', 9) and the second (2', 9') wall regions in the direction respectively of the second (2', 9') and the first (1', 9) wall regions. The separating region or regions of the separating elements has (have) a height (h) less than the distance (D) between the first (1', 9) and the second (2', 9') wall regions. The agitator includes a first and second devices (7) for moving the two housing elements (1, 2) with respect to each other.
Claims10
Bioreactor for use under microgravity conditions comprising:
- at least one cell culture chamber,
- an oxygen supply for at least one chamber;
- and
- an agitator for agitating a cell culture so as to enable contact with oxygen supplied to said chamber, said chamber comprises:
- (i) a first and a second housing element having respectively a first and a second wall region which face each other, with said first and second having elements being separated by a distance (D);
- (ii) a first separating element comprising at least one first separating region extending from the first wall region towards the second wall region;
- (iii) a second separating element comprising at least one second separating region extending from the second wall region towards the first wall region, wherein the first and second separating elements are separated by a distance (d) and the separating region or regions of at least one of the separating elements have a height (h) less than the distance (D), and said agitator comprises (i) a first device displacing the first and the second housing elements with respect to each other so as to vary the distance (d) between the first and second separating elements, and (ii) a second device for displacing the first and the second housing elements with respect to each other so as to vary the distance (D) between said first and second housing elements.
