We claim: 1. A device for trapping extraneous gas or bubbles comprising: one or more surfaces defining an internal volume; said one or more surfaces comprising a top surface, a bottom surface, sidewalls and/or end walls; and a gas collection area incorporated within said internal volume; said gas collection area defined by a flange extending from said one or more surfaces within said internal volume; wherein said gas collection area is included in the tapered neck portion; whereby when said internal volume is substantially filled with a liquid and tilted, said gas collection area traps said extraneous gas. 2. The device according to claim 1, wherein said gas collection area is defined by a flange extending from said one or more surfaces in combination with a surface of said tapered neck portion. 3. The device according to claim 2, wherein said flange is disposed radially or circumferential to said opening. 4. A device for trapping extraneous gas or bubbles comprising: one or more surfaces defining an internal volume; said one or more surfaces comprising a top surface, a bottom surface, sidewalls and/or end walls; wherein said internal volume includes a plurality of cell growth layers or chambers; a gas collection area incorporated within said internal volume; whereby when said internal volume is substantially filled with a liquid and tilted, said gas collection area traps said extraneous gas; and wherein the device is a cell growth apparatus. 5. The device of claim 4, wherein the device further comprises a manifold. 6. The device of claim 4, wherein said tapered neck portion in combination with said opening allows access to said internal volume. 7. The device of claim 4, wherein said tapered neck portion is narrowed. 8. The device of claim 4, wherein said tapered neck portion comprises said gas collection area.
