In use, the stopcock is opened to equalize the system with ambient pressure. After closing the valve again, the bulb is immersed in a succession of liquids of known temperatures. The pressure and temperature readings are recorded on a typical X-Y graph, with pressure on one axis and temperature on the other axis. By extrapolating the line created by the plotted points on the graph, the point at which pressure would equal zero can be determined. The corresponding temperature at this point is an approximation of Absolute Zero. Available also with a bicycle-type air valve instead of a stopcock.
