Ganong Potometer Apparatus
Product Code : JC-PE-7578
The Ganong Potometer Apparatus (SKU JC-PE-7578) demonstrates transpiration and the rate of water absorption by a cut shoot under different external conditions. The shoot is sealed into a stopper in the end tube, the apparatus is filled with water and the open end of the 1 mm bore capillary dips into a beaker. Opening the glass stopcock admits water from the reservoir to reset the air bubble. The Ganong potometer is made by JaincoLab on a varnished wooden base with spring clips.
