Ganong Potometer Manufacturer,Supplier and Exporter in India
Product Code : EL-BL-11885
Jlab Export is a leading Ganong Potometer Manufacturer,and suppliers in India
Ganong Potometer (code EL-BL-11885) is a borosilicate glass potometer, model JL209/033, for measuring how fast a leafy plant shoot takes up water. Students use it to follow transpiration, since most of the water a shoot draws up is lost from its leaves. JLab makes the JL209/033 potometer in Ambala, India.

How a Reading Is Taken
The apparatus is filled with water and a freshly cut shoot is fitted into it airtight. As the leaves lose water, the shoot draws more in, and a small air bubble let into the glass tube moves along it. Timing how far the bubble travels gives the rate of uptake; several readings under the same conditions give a fair average.
What It Shows in a Lesson
Because uptake follows the rate of transpiration, one shoot can be compared in still and moving air, in light and shade, or before and after some leaves are coated with petroleum jelly. When the bubble moves faster, the change has speeded up water loss from the leaves; when it slows, loss has dropped.
Frequently Asked Questions
Does the potometer measure transpiration directly?
No. It measures the water the shoot takes up. A small part of that water is used by the plant’s cells, so the uptake rate is a close estimate of transpiration rather than an exact measure.
Why is the shoot cut under water?
Cutting and fitting the stem under water stops air entering the xylem vessels that carry water. An air lock there breaks the water column and slows or stops uptake, which gives false readings.
