The vessel of claim 1 wherein the base comprises at least one protrusion. 11. The vessel of claim 1 wherein the at least one protrusion is comprised of a surface that is non-reactive to the precursor material contained therein. 12. The vessel of claim 1 wherein the at least one protrusion has a cloverleaf design. 13. The vessel of claim 1 wherein at least one protrusion extends from the sidewall. 14. The vessel of claim 1 wherein the fluid inlet further comprises a tube that directs the flow of a carrier gas into the upper volume and across the sidewall of the vessel. 15. The vessel of claim 14 wherein the tube is "T" shaped. 16. The vessel of claim 1 wherein the fluid outlet further comprises a tube that directs the flow of the precursor-containing fluid out of the vessel. 17. The vessel of claim 16 wherein the tube is "T" shaped. 18. The vessel of claim 1 wherein the lid is removable. 19. The vessel of claim 15 wherein the "T" shaped tube forming the fluid inlet has at least one angled end. 20. The vessel of claim 17 wherein the "T" shaped tube forming the fluid outlet has at least one angled end. 21.
