Abstract
A compact, easily assembled cell culturing device comprising at least one cell culturing envelope, the interior of which defines a cell culturing space. The cell culturing envelope is retained within a pair of rigid plates having various reliefs which, in turn, form cavities when the plates are placed together. The cell culturing envelope includes a plurality of hollow fibers disposed in the culturing space formed between upper and lower membrane sheets which are sealed together. Tubes communicate with the culturing space. Accordingly, greater amounts of oxygen are provided to the cells at a faster rate to produce cells and/or cell products more economically and in higher yield.
