About This Product
Transpiration is the loss of water vapour from the leaves of a plant. A potometer measures how fast a cut shoot takes up water, which is used as an estimate of the transpiration rate, because most of the water absorbed is lost through the leaves. Students compare the rate of uptake under different conditions such as light, wind, humidity and temperature by noting how far the water column or air bubble moves along the graduated capillary tube in a set time. The Potometer can be supplied and exported to buyers in Benin, Uzbekistan, Costa Rica, Liberia, Angola and Portugal.
Frequently Asked Questions
Q1. What is the Potometer used for?
It is used to demonstrate rates of transpiration and rates of water absorption by a cut shoot under various external conditions.
Q2. How is the Potometer set up?
A plant shoot is sealed into a stopper that fits the end tube. The whole apparatus is filled with water, and the open end of the capillary tube, graduated in millimetres, dips into a beaker of water.
