GANONG’S POTOMETER
To demonstrate transpiration rate and rate of water absorption by a cut shoot under various external conditions. A plant shoot is sealed into a stopper which fits the end tube, central reservoir is attached to the tube by a stopcock. End of tube is connected to a capillary tube graduated in millimeters. One end of which is dipped into a beaker having water. The whole apparatus is filled with water. An air bubble is introduced by lifting the capillary tube out of water, and the rate at which bubble is drawn along the tube is proportional to the rate of water loss by the shoot. The position of an air bubble is adjusted by opening the glass stopcock to admit water from central reservoir. The whole apparatus is mounted on a polished wooden or bakelite base by spring clips.
GANONG POTOMETER
A potometer is a device, which is used to measure water uptake by the plant shoot during transpiration. It is also known as transpirometer. Ganong’s potometer is used to measure the transpiration rate in a laboratory.
Superior Ganong Potometer is Made up of Borosilicate 3.3 Glass with Glass Stopcock om Wooden Base.
Used in Biological Laboratories For demonstration of transpiration rates and rates of water absorption by a cut shoot under various external conditions.
Ganong Potometer is a Glass apparatus used for measuring the rate of water uptake of a leafy shoot from water reservoir.
Consist of a Graduated capillary tube, which is graduated in millimeter, dipping into beaker of water.
Ganong’s Potometer typically consists of a water reservoir, which holds the water that will be supplied to the plant. The reservoir is often equipped with a graduated scale for accurate measurement of the water level.
Ganong Potometer is on Stable Wooden Base.
