Abstract
The siphoning device, with measuring indicators, is used for liquid-liquid separation. The body member has an outlet with an open tip; the outlet can have a peripheral rim with notches proximate the open tip. A two-way liquid valve contoured to approximate the contour of the interior of the outlet, controls liquid flow out of the body and permits flow into the body. A stem portion affixed to the liquid valve extends through and beyond the open tip of the outlet. Pressure on the stem places the valve in an open position and permits liquid to be discharged. An air pump interacts with the body to expel air and draw in the liquids. Generally the air pump is a flexible bulb with a one-way air valve to restrict air flow into the hollow body while permitting air flow out. The hollow body can be in two parts which are removably connected to one another. The travel of the liquid valve within the hollow body is limited by stops.
