Potometer

Potometer Determination of transpiration in plant leaves is aim of laboratory Potometer. It has a graduated, narrow bore, horizontal glass measuring tube with a vessel for a plant shoot at one end along with a vertical limb and stopcock and a funnel fitted by a ground glass joint. It is mounted on a wooden stand and is 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, the open end of the capillary tube, which is graduated in millimetres, dipping into a beaker of water Height to top of reservoir: 170mm Diameter of reservoir: 20mm Overall Length: 320mm Base: 320 × 80 mm (L × W) Capillary bore: 1mm
