Abstract: An apparatus and method for analyzing a fluid wherein the apparatus comprises a transparent elongate body having a piston within a central cavity therein. The piston includes a first sealable chamber and defines a second chamber between the second end of the elongate body and the piston. The apparatus includes an opening through the second end of the elongate body and an actuator operably connected to the piston so as to draw the piston away from the opening so as to draw a second fluid into the second chamber. The method comprises introducing a volume of a control fluid into the first chamber and drawing the piston in a direction away from a second end of the elongate body so as to draw a volume of a sample fluid into the second chamber so as to permit visual comparison of the control and the sample fluids.

Abstract: Disclosed is an apparatus and method for analyzing a fluid. The apparatus comprises an elongate body having a piston therein defining first and second chambers within the elongate body, an opening through the elongate body in fluidic communication with the second chamber and an actuator operably connected to the piston so as to draw the piston away from the opening. At least a portion of the elongate body is transparent so as to permit a visual comparison of the second fluid and a first fluid contained within the first chamber. The method comprises introducing a volume of a control fluid into the first chamber, slidably and sealably moving the piston in a direction away from the opening so as to draw a volume of a sample fluid into the second chamber and visually comparing the control and the sample fluids to each other.
