Gagnon's Potometer Accuracy is +/- 5nmFor the demonstration of transpiration rates and rates of water absorption by a cut shoot under various external conditions. The whole apparatus is filled with water and a plant shoot is sealed into a stopper which fits the end tube. The open end of the capillary tube, which is graduated in millimeters, is placed into a beaker of water. An air bubble is generator by dipping the graduated tube out of and back into a beaker of water. The air bubble can
