Abstract
A bioreactor for culturing of cells is described. Screens suitable as a cell growth scaffold may comprise crossed fibers. Screens may be contained loosely in a screen holder, which in turn may be contained inside a manifold assembly. A lower manifold, screen holder and upper manifold may have identical or similar interior open cross-sections. Flow of liquid medium can occur upwardly through the array of screens, then flowing over a weir in the presence of an air pocket, and into a moat and a pump. The screen holder may have slots whose exterior-facing ligaments are rounded, and may have grooves whose interior-facing edges are rounded. These components may be located inside an incubator suitable to maintain desired environmental conditions and cleanliness.
