About This Item
Description
A potometer is an apparatus used for measuring the rate of water uptake of a leafy shoot. The causes of water uptake are photosynthesis and transpiration. This potometer can be used for demonstration of transpiration rates and rates of water absorption by a cut shoot under various external conditions. A plant shoot is sealed into a stopper which fits the end tube, and the whole apparatus is filled with water (with the open end of the capillary tube, which is graduated in millimeters), and then dipping into beaker of water. The position of the air bubble may easily be adjusted by opening the glass stopcock to admit water from the reservoir. Potometer is mounted on wooden base by clips; base measures 12-1/4 inches wide, with height to top of reservoir at approximately 6-1/2 inches. Reservoir diameter is approximately 3/4 inches; capillary bore diameter is 1 millimeter. Instruction manual included.
