Abstract: An extraction apparatus including an extraction device for facilitating the mixing of a predetermined volume of immiscible liquids and subsequently separating and dispensing a selected one of the liquids. The apparatus includes a tubular member with an extraction chamber which communicates with a collection chamber through a U-tube, the relative location of the extraction chamber, the collection chamber and the U-tube enabling such mixing and enabling the selected liquid to be passed subsequently from the extraction chamber to the collection chamber by manipulation of the tubular member. Further manipulation of the tubular member enables the collected selected liquid to be dispensed to a test tube while the remaining unwanted liquid is drained from the extraction chamber. A plurality of extraction devices enable multiple mixing and separating operations to be performed simultaneously in a single apparatus by a single operator.
