Abstract
A perfusion incubator having a fluid conditioning unit (12), a well assembly (7) and a well assembly heating unit (14), a peristaltic pump (4) and a fluid collection unit (11). The well assembly has a number of wells (20, 21) each having a transparent lid (30) and a fluid inlet (26) and a fluid outlet (27). An illumination device (13) is under the well so that the cell being cultured in the well assembly can be observed by means of a microscope (15). Each fluid inlet (26) is positioned so as to allow a tangential entry of fluid to the well at a mid point in the well, and each fluid outlet (27) is above the fluid inlet with the cell to be cultured in a lower portion of the well so that flow of fluid in the well is formed into a vortex which tends to draw fluid from around the cell without direct flow over the embryo.
