ABSTRACT:
A device for adapting a liquid container to enable separation and selective dispensation of two or more immiscible liquids of different densities from the container. The device comprises (a) a first liquid conduit adapted at one end for detachable attachment to the container, whereby the first conduit and the interior of the container may be placed in fluid communication with one another, (b) at least one wall forming a liquid reservoir, the other end of the first conduit opening into the reservoir at a first liquid passage to place the interior of the container in liquid communication with the reservoir, and (c) a second liquid conduit which at one end opens into the reservoir at a second liquid passage and at the other free end opens to an exterior of the container, thereby placing the reservoir in liquid communication with the exterior, wherein the first and second liquid passages are spaced apart from one another and disposed relative to the reservoir such that liquids from the container can form separate phases in the reservoir when dispensed from the container and through the first conduit and the liquid(s) of lesser density or densities can be dispensed from the reservoir through the second liquid passage while the liquid(s) of greater density or densities remain in the reservoir. Methods of separating and selectively dispensing two or more immiscible liquids of different densities from a container, as well as methods for adapting a container to enable separation and selective dispensation of two or more immiscible liquids of different densities from the container are also disclosed.
