Potometer Apparatus "H" Type Manufacturer,Supplier and Exporter in India
Product Code : EL-PE-7577
Jlab Export is a leading Potometer Apparatus "H" Type Manufacturer,and suppliers in India
Potometer Apparatus "H" Type (code EL-PE-7577) is a student potometer for measuring how fast a cut shoot takes up water in transpiration practicals in school and college biology labs. The shoot is attached to the side arm with tubing, the wide glass tube acts as the reservoir, and the water movement is followed along a 140 mm capillary tube. 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 | Other listed details |
|---|---|---|
| This potometer (EL-PE-7577) | H type; cut shoot on the side arm with tubing; wide glass tube as reservoir | 140 mm capillary, 1 mm bore; 160 x 20 mm glass tube; 8 mm side arm; individual student use |
| Potometer Student | H type; cut shoot on the side arm with tubing; glass tube as reservoir | Suitable for students; dimensions not stated in its listing |
| Ganong Potometer Apparatus | Shoot sealed into a stopper in the end tube; glass stopcock admits water from a reservoir to reset the air bubble | Mounted on a varnished wooden base with spring clips; listed for demonstrating transpiration rates |
| Potometer Apparatus White Stand | Apparatus is submerged and the shoot placed in the tube | A syringe is used to zero the scale |
Choose this H-type apparatus when each student or pair needs a compact set with stated dimensions. The Ganong model, fixed on a wooden base with a stopcock for resetting the bubble, suits a demonstration on the teacher’s bench, and the white-stand model zeroes its scale with a syringe.
What Is the H-Type Potometer Used For?
A potometer measures the rate at which a leafy shoot draws up water. Because most of the water a shoot absorbs is lost by evaporation from its leaves, the uptake rate is used in class as a practical measure of transpiration. With this apparatus students compare the rate under different conditions — still air against moving air from a fan, light against shade, or leaves left open against leaves smeared with petroleum jelly — in secondary-school lessons on transport in plants and in college botany and plant physiology labs. It is a simple transpiration experiment kit for plant biology lab work.
Cut the shoot under water so that no air enters the stem, fit it into the tubing on the side arm, fill the apparatus with water and make every joint airtight. Then mark the position of the water meniscus or a small air bubble in the capillary and time how far it moves; multiplying the distance by the cross-sectional area of the 1 mm bore converts it to a volume of water taken up. After use, rinse the glass with clean water, let it dry and handle the narrow capillary with care.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; for individual student use, plan one per student or pair plus a few spares.
- Model — this H-type apparatus, the student potometer, the Ganong apparatus on a wooden base or the white-stand version.
- Stands and other items — say if you also need stands, clamps, beakers or stopwatches so they can be quoted as separate catalogue items.
- Delivery details — destination country and city, delivery terms and any packing or labelling needs for glassware.
Frequently Asked Questions
What are the dimensions of this potometer?
The capillary tube is 140 mm long with a 1 mm bore, the wide glass reservoir tube is 160 mm long and 20 mm in diameter, and the side arm is 8 mm in diameter.
How is the plant shoot fitted?
The cut shoot is attached to the side arm with tubing. Cut the stem under water and seal the joint so that air cannot leak in, otherwise the reading will drift.
Does a potometer measure transpiration directly?
Not exactly. It measures how much water the shoot takes up. Most of that water is lost through the leaves, so the uptake rate is a close practical estimate of transpiration, but a small share is used by the shoot itself.
How is it different from the Ganong Potometer Apparatus?
This H-type model is a compact apparatus for individual student use. The Ganong apparatus is mounted on a varnished wooden base with spring clips and has a glass stopcock that admits water from a reservoir to reset the air bubble, so it suits demonstrations.
Is a stand or clamp included?
This listing does not mention a stand or clamp. Tell JLab what support you need and it can be quoted alongside the potometers.
What should an export enquiry include?
The quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling needs and, for a tender, its reference number.
Who manufactures this potometer?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of biology and science laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The H-type potometer is made at JLab’s own works and is not bought in from a trader, so schools, colleges, dealers and importers buy it factory-direct; every set is visually inspected before it is packed, and repeat orders are handled by the manufacturer itself. JLab exports worldwide and ships to buyers in every region, for example Sri Lanka in South Asia, Mongolia in East Asia, Lesotho in Southern Africa, Ghana in West Africa and Uganda in East Africa. Tender buyers can find details on the JLab lab tenders page.
