Patent ID: 7160359

Claim:
An apparatus for containing and dispensing a high purity fluid comprising an outer vessel capable of containing a quantity of high purity fluid in its interior; an outlet associated with the outer vessel for dispensing the high purity fluid; a valve assembly capable of controlling high purity fluid flow out of the outer vessel through the outlet; a separate fill path in the valve assembly with a second valve for controlling fluid flow through the separate fill path wherein an inlet for the separate fill path is the same as the outlet associated with the outer vessel; an inner vessel at least partly situated in the outer vessel and communicating with the outlet and having an inlet which communicates with the interior of the outer vessel; purification media contained within the inner vessel for purifying the high purity fluid of undesired components; and a fluid flow control device which prevents high purity fluid from flowing from the inner vessel to the interior of the outer vessel; wherein the purification media is selected from the group consisting of fluorisil, cross-linked microporous polymers, magnesium sulfate, barium on carbon, magnesium chloride on carbon, magnesium chloride on alumina, magnesium bromide on carbon, palladium on carbon, stainless steel mesh, sintered nickel, sintered stainless steel, and mixtures thereof.
