As used herein, a cell encapsulation device comprising an internal chamber suitable for holding a biological agent, wherein the internal chamber is disposed between a first semipermeable layer and a second semipermeable layer. And the first and second semipermeable layers are attached to a support frame that surrounds the interior chamber, the support frame comprising a first frame element and a second frame element and the first and second frames. The frame elements cooperate to provide a cell encapsulating device in which the first and second semipermeable layers are positioned such that there is a predetermined separation between the layers.
