Potometer Manufacturer,Supplier and Exporter in India
Product Code : JA-ELA-5401
The Potometer (SKU JA-ELA-5401) is a glass apparatus on a wooden stand, made by JaincoLab, for measuring transpiration in plant leaves. A cut shoot is sealed into a stopper at one end, the apparatus is filled with water, and the open end of the horizontal capillary dips into a beaker of water. As the shoot draws water, the movement along the capillary, graduated in millimetres, shows the rate of uptake.
Specifications
The potometer has a 1 mm bore capillary, a 20 mm diameter reservoir 170 mm high, an overall length of 320 mm and a 320 x 80 mm base, as given in the product data.

Experiments with the potometer
The potometer measures the rate of water uptake by a cut shoot, which closely follows transpiration, and lets that rate be compared under different external conditions.
- Measuring the rate of transpiration of a leafy shoot
- Comparing water uptake in still and moving air, light and shade
- Showing the effect of temperature or humidity on transpiration
- Plant physiology practicals in school biology and B.Sc. botany
