Potometer Manufacturer,Supplier and Exporter in India
Product Code : EL-ELA-5401
Jlab Export is a leading Potometer Manufacturer,and suppliers in India
Potometer (code EL-ELA-5401) is a plant physiology apparatus for studying transpiration in plant leaves, used to demonstrate how fast a cut shoot takes up water under different external conditions in school and college biology labs. A horizontal capillary tube graduated in millimetres, with a 1 mm bore, carries the shoot vessel at one end, and the whole unit sits on a wooden stand. 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 details |
|---|---|---|
| This potometer (EL-ELA-5401) | Horizontal capillary tube graduated in millimetres; shoot vessel at one end; vertical limb with stopcock and funnel on a ground glass joint | Wooden stand; full dimensions and capillary bore listed |
| Ganong Potometer | Graduated narrow-bore glass tube linking a vessel for the shoot with a funnel and glass stopcock | Wooden stand included; dimensions not stated |
| Potometer Student | H-type; cut shoot attached to the side arm with tubing; glass tube acts as the reservoir | Student model; dimensions not stated |
| Darwin Potometer | Glass tube; straight limb closed at the top with a rubber stopper; bored stopper at the lower end takes capillary tubing | Dimensions not stated |
Choose this potometer when you want a stand-mounted demonstration unit with a millimetre-graduated capillary and published dimensions, and a funnel and stopcock for resetting the reading. The Ganong listing describes a similar tube, funnel and stopcock layout, the student H-type model suits one set per bench, and the Darwin potometer is a simpler stoppered-tube design.
What Is the Potometer Used For?
A potometer measures the rate at which a leafy shoot takes up water. Because nearly all the water a shoot absorbs is lost from its leaves by transpiration, the uptake rate is used as a measure of transpiration rate in the plant physiology topics of secondary biology (for example ICSE class 10) and in college botany practicals. Students compare readings in still and moving air, light and shade, or warm and cool conditions to see how the environment affects water loss.
To set it up, cut the shoot under water so that no air enters the xylem, seal it into the stopper and fit it to the shoot end, then fill the apparatus with water through the funnel with the stopcock open, keeping the open end of the capillary in a beaker of water. Lift the capillary end out of the water for a moment to let in a single air bubble, put it back, and time how many millimetres the bubble travels. Opening the stopcock lets water from the funnel push the bubble back to the start. Multiplying the distance moved by the cross-sectional area of the bore (πr²) gives the volume of water taken up.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; one per group of students is typical for practical classes.
- Beakers and timers — separate catalogue items that can share the enquiry.
- Plant material — not supplied; a fresh leafy shoot is cut for each run.
Frequently Asked Questions
What does a potometer measure?
The rate of water uptake by a cut leafy shoot. This is taken as a measure of transpiration, which is the purpose stated for this apparatus, and it can be compared under different external conditions.
What are the dimensions of this potometer?
The height to the top of the reservoir is 170 mm, the reservoir diameter 20 mm and the overall length 320 mm. The wooden base measures 320 x 80 mm and the capillary bore is 1 mm.
How is the reading taken?
An air bubble is let into the capillary and its movement along the millimetre graduations is timed. Opening the stopcock lets water from the funnel reset the bubble for the next reading.
How does it differ from the Ganong Potometer listing?
Both describe a graduated narrow-bore tube, a shoot vessel, a funnel and a stopcock on a wooden stand; only this listing gives the dimensions and the ground glass joint, so ask JLab if another detail decides your choice.
Are the beaker and plant shoot included?
No. The listing covers the potometer on its stand. A beaker of water is needed for the open end of the capillary and can be ordered separately; the shoot is cut fresh for each experiment.
What is the minimum order and dispatch time?
The minimum order is 10 units, sold individually, and orders are usually dispatched within 7–10 working days after each potometer has been visually inspected. Export transit time depends on the destination.
What information is needed for an export quotation?
The quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and a tender reference if there is one.
Who manufactures this potometer?
JLab (Jain Laboratory Instruments Pvt Ltd) builds it at its works in Ambala, Haryana, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a botany and biology lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The potometer’s glassware and wooden stand are made at JLab’s own works rather than bought in, so schools, colleges, dealers and importers buy factory-direct, every unit is visually inspected before packing, and replacement parts and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — Kyrgyzstan in Central Asia, Mexico in North America, Serbia in Southern Europe, Bolivia in South America and Hong Kong in East Asia are some examples. For institutional purchasing, see the JLab lab tenders page.
