Abstract:

A device and method for extending the useful life of a bulk liquid used in an automated clinical analyzer. Air from the atmosphere surrounding the automated clinical analyzer that displaces the bulk liquid consumed from a container is routed through a gas scrubber in order to remove or at least reduce the quantity of at least one contaminant present in that air. The gas scrubber is positioned between the bulk liquid in the container and the atmosphere surrounding the container. The gas scrubber contains a reagent that is capable of reacting with a contaminant in the atmosphere, whereby a required characteristic(s) of the bulk liquid does (do) not change excessively prior to the date that the bulk liquid is consumed. For example, if the contaminant is carbon dioxide, and the required characteristic of the bulk liquid is the level of pH of the bulk liquid, the reagent in the gas scrubber prevents the level of pH of the bulk liquid from changing excessively prior to the date that the bulk liquid is consumed.
