Claim:
1. A chemical reactant source vessel comprising; a container body; a lid adapted to engage the container body, the container body and the lid together defining an internal chamber adapted to contain a solid or liquid chemical reactants wherein a width of the lid is greater than an overall height of the container body; a first passage extending through the lid, the first passage extending from the internal chamber to outside the container, wherein the lid comprises an inner surface and an outer surface; a second passage extending through the lid, the second passage extending from the internal chamber to outside the container; an outlet valve attached to the outer surface of the lid without any tubing between the outlet valve and the outer surface, thereby conforming a temperature of the outlet valve to that of the lid, the outlet valve adapted to regulate gas flow through the first passage; an inlet valve attached to the outer surface of the lid without any tubing between the inlet valve and the outer surface, thereby conforming a temperature of the inlet valve to that of the lid, the inlet valve adapted to regulate gas flow through the second passage; a serpentine path insert in the internal chamber, wherein the serpentine path insert contacts the lid, thereby defining a serpentine gas flow path, wherein the first and second passages join the serpentine gas flow path at or near opposite ends of the serpentine gas flow path, wherein the serpentine gas flow path is configured for sublimation, vaporization, or sublimation and vaporization of a chemical reactant in the serpentine path at temperatures that facilitates reliability of the inlet valve and outlet valve, and wherein the source vessel is configured to be received in a gas interface assembly positioned such that a heater above said vessel heats said valves and said vessel, and wherein the temperatures of sublimation, vaporization, or sublimation and vaporization and the temperature conformity of the inlet valve, outlet valve, and lid expedite heating of the source vessel and facilitate saturation of the chemical reactant in a carrier gas; and a first filter on the inner surface of the lid, the first filter adapted to prevent particulate matter from flowing through the first passage.
