Ganong Potometer Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-PE-7578
Jlab Export is a leading Ganong Potometer Apparatus Manufacturer,and suppliers in India
Ganong Potometer Apparatus (code EL-PE-7578) is a Ganong’s potometer for demonstrating transpiration rates and the rate of water absorption by a cut shoot under various external conditions in biology teaching labs. A glass stopcock admits water from a reservoir so the air bubble in the 1 mm bore capillary can be reset, and the whole set is clipped to a varnished wooden base. 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 | Mounting and other listed details |
|---|---|---|
| This apparatus (EL-PE-7578) | Shoot in a stopper on the end tube; glass stopcock and reservoir to reset the bubble; 1 mm capillary bore | Varnished wooden base with spring clips; for demonstrating transpiration and water absorption |
| Ganong Potometer | Graduated narrow-bore glass tube with a shoot vessel at one end and a funnel with glass stopcock at the other | Complete with wooden stand; measures the rate of water uptake of a leafy shoot |
| Potometer Ganong (For Photosynthesis) | Ganong’s potometer for transpiration rate and water absorption by a cut shoot | Dimensions and stand not stated in its listing |
| Ganog’s Potometer | Borosilicate glass | Listed for measuring water uptake by a leafy shoot |
| Potometer Apparatus “H” Type | H type; cut shoot on the side arm with tubing; wide glass tube as reservoir | Compact, for individual student use |
Pick this apparatus when the teacher wants a mounted Ganong set whose bubble can be reset quickly between readings. If you need a graduated tube, the Ganong Potometer with funnel and wooden stand lists one; for a set on every student bench, the H-type potometer is the compact option.
What Is the Ganong Potometer Used For?
The Ganong’s potometer shows how quickly a leafy shoot absorbs water and, from that, how fast it transpires. Teachers use it to demonstrate the effect of external conditions on transpiration — bright light against shade, a fan against still air, or a dry room against a humid one — in secondary-school biology lessons on transport in plants and in college botany and plant physiology practicals. It belongs with the plant biology lab equipment on a botany practical bench.
For a reading, the shoot is cut under water and sealed into the stopper on the end tube, the whole apparatus is filled with water, and the open end of the capillary stands in a beaker of water. Lifting that end out of the beaker for a moment lets in an air bubble; as the shoot draws up water, the bubble travels along the capillary, and the distance moved in a set time, multiplied by the cross-section of the 1 mm bore, gives the volume absorbed. When the bubble nears the end, open the glass stopcock briefly to push it back with water from the reservoir and start the next run. Rinse the glassware after use and keep the wooden base dry.
What to Specify When Ordering
- Number of sets — the minimum order is 10 units; demonstration sets are often ordered one per teaching lab plus spares.
- Model — this mounted apparatus, the Ganong Potometer with graduated tube and funnel, or the H-type student potometer.
- Base dimensions — ask us to confirm the base size listed here before ordering if it matters for your bench or storage.
- Beakers — add beakers for the capillary end if your lab needs them; they are separate catalogue items.
Frequently Asked Questions
How is the air bubble reset between readings?
By opening the glass stopcock. Water from the reservoir flows in and moves the bubble back along the capillary, so a new reading can start without dismantling the apparatus.
What is the capillary bore?
The capillary bore is 1 mm. A narrow bore makes a small uptake of water show as a clearly visible movement of the bubble.
Does the apparatus measure transpiration or water absorption?
It is listed for both. Strictly it measures water absorbed by the cut shoot; because most of that water is lost from the leaves, the absorption rate is used as a practical measure of the transpiration rate.
Is a beaker included?
The listing describes dipping the open end of the capillary into a beaker of water but does not list a beaker as part of the apparatus. Add beakers to the same enquiry if you need them.
How does it differ from the H-type potometer?
This Ganong apparatus is clipped to a varnished wooden base and has a stopcock and reservoir for resetting the bubble, which suits demonstrations. The H-type potometer is a compact apparatus listed for individual student use.
What details does an export quotation need?
Send the quantity, destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling requirements and the tender reference if one applies.
Who manufactures the Ganong Potometer Apparatus?
JLab — Jain Laboratory Instruments Pvt Ltd — makes it at its Ambala works in Haryana, India, and supplies it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a school and college laboratory equipment manufacturer in India, incorporated in 2017, with its base on Hargolal Road, Ambala, Haryana. This potometer is produced in JLab’s own works, not sourced from a trader, which lets schools, colleges, dealers and importers order it factory-direct; each one is visually inspected before dispatch and the manufacturer looks after repeat orders. JLab exports worldwide and can ship to every region — Vietnam in Southeast Asia, Tanzania in East Africa, Senegal in West Africa, Colombia in South America and Lithuania in Northern Europe are some examples. Tender buyers will find more on the JLab lab tenders page.
