Potometer Ganong (For Photosynthesis) Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4687
Jlab Export is a leading Potometer Ganong (For Photosynthesis) Manufacturer,and suppliers in India
Potometer Ganong (For Photosynthesis) (code EL-SLE-4687) is a Ganong’s potometer, a plant physiology apparatus for observing the transpiration rate and the rate of water absorption by a cut shoot under various external conditions in school and college biology labs. Students change light, air movement or temperature and watch how fast the shoot takes up water. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Potometers?
| Model | Listed design | Listed use |
|---|---|---|
| This potometer (EL-SLE-4687) | Ganong type; details to be confirmed with the quotation | Transpiration rate and water absorption by a cut shoot under various external conditions |
| Ganong Potometer | Graduated narrow-bore glass tube with a vessel for the shoot at one end and a funnel with glass stopcock at the other; wooden stand | Rate of water uptake of a leafy plant shoot |
| Ganong Potometer Apparatus | Shoot sealed into a stopper that fits the end tube; apparatus filled with water | Transpiration rates and water absorption by a cut shoot |
| Potometer Apparatus “H” Type | Cut shoot attached to the side arm with tubing; wide glass tube as reservoir | Individual student use |
Choose a Ganong-type potometer for teacher demonstrations and group practicals where the rate is read along a horizontal graduated tube; the H-type model is the simpler choice when every student needs a set of their own.
What Is the Ganong’s Potometer Used For?
A potometer measures how quickly a leafy shoot draws up water. The shoot is cut and fitted to the apparatus under water so that no air enters the stem, the apparatus is filled with water, and an air bubble is let into the graduated tube. As the leaves lose water vapour through their stomata, the shoot pulls water in and the bubble moves along the scale; the distance moved in a set time gives the rate. In Ganong’s design the reservoir is used to push the bubble back to the start, so the same shoot can be tested again under a new condition, such as bright light and darkness, still air and a fan, or a warm and a cool room. Since only a small part of the water taken up is used in photosynthesis and growth, the uptake rate is a close guide to the transpiration rate.
The apparatus supports the topic of transpiration in class 10 science (Life Processes) and plant physiology practicals in senior-secondary and college botany labs. For good results, cut the shoot under water, seal every joint so it is airtight, keep the leaves dry, let the shoot settle for a few minutes before timing, and take several readings under each condition.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; a Ganong’s potometer is often one per bench, with H-type sets for individual students.
- Design details — ask JLab to confirm the stand, the scale on the graduated tube and the shoot fitting before you order.
- Spares — rubber stoppers, tubing and petroleum jelly or sealant for airtight joints can be added to the same enquiry.
Frequently Asked Questions
What does a Ganong’s potometer measure?
It measures the rate at which a cut shoot takes up water, which is close to its transpiration rate. Readings are compared under various external conditions such as light, air movement and temperature.
Does this potometer measure photosynthesis?
No. Despite the “(For Photosynthesis)” in its catalogue name, it measures water uptake, not oxygen output or carbon dioxide uptake. It fits into plant physiology lessons because light, which drives photosynthesis, also opens the stomata and raises the transpiration rate.
How do I take a reading?
Fit the freshly cut shoot under water, make every joint airtight, let in a single air bubble and time how far it moves along the graduated tube. Reset the bubble from the reservoir before testing the next condition.
How is it different from the H-type potometer?
The H-type model is listed for individual student use, with the cut shoot on a side arm and a wide glass tube as the reservoir. The Ganong type uses a horizontal graduated tube with a reservoir to reset the bubble, which suits demonstrations and repeated readings on one shoot.
What should I send for an export quotation?
Send the quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling requirements, and the tender reference if one applies.
Who manufactures this potometer?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a biology and plant physiology lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This potometer is made at JLab’s own works, not bought in from a trader, so schools, colleges, dealers and importers buy it factory-direct, each unit is visually inspected before dispatch, and repeat orders and spare parts are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Chile in South America, Rwanda in East Africa, El Salvador in Central America and the Caribbean, Mongolia in East Asia and Iraq in the Middle East. For tenders, see the JLab lab tenders page.
