Abstract
A cell cultivating device comprising superposed, separate partition wall members forming mutually spaced partition walls, which define superposed chambers for containing a cell cultivating medium therebetween. The superposed partition wall members each comprising said partition wall and an upstanding peripheral wall extending transversely thereto, are arranged within a closed outer container having a flat bottom wall and a flat end wall. A liquid cultivating medium may be introduced into the outer container through a filling opening while the container is in an upright position in which it is supported by the end wall. The liquid may then substantially uniformly distribute itself within the cultivating chambers via a tunnel extending along the end wall and interconnecting the cultivating chambers. The partition wall members are preferably sealingly interconnected along the periphery thereof, and the free end of the upper partition wall member may be spaced from the inner surface of the container top wall in order to reduce problem of leakage of liquid medium between the chambers.
