Potometer Apparatus Manufacturer,Supplier and Exporter in India

Potometer Apparatus (Product Code: SLE/EBT/21) is a low-breakage student potometer used to measure transpiration in small plant shoots during school and college biology practicals. Its only glass component is the capillary tube, mounted on a strong backing plate, and a syringe zeros the scale between readings. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as a transpiration experiment kit that groups can use with minimal risk of breakage.

What Is the Potometer Used For?

Teachers use this potometer to show that leaves lose water continuously and that the rate changes with the surroundings. A typical practical compares how far the bubble travels in a fixed time with the shoot in still air, beside a fan, in bright light and in shade, so students can link wind, light and humidity to the rate of water loss. Because the apparatus is assembled under water, air is kept out of the system, and the syringe brings the bubble back to zero between runs without dismantling anything.

For reliable results, cut the shoot under water so that air does not enter the stem, fit it firmly before lifting the apparatus out, and blot the leaves dry before taking readings. Strictly, a potometer measures the water taken up by the shoot; this closely follows transpiration because most absorbed water leaves through the leaves — a useful discussion point for older students. With a porous pot connected in place of the shoot, the same unit can be used to compare humidity.

What to Specify When Ordering

• The number of potometers needed, usually one per student group.
• Whether you plan humidity measurements, so we can confirm whether a porous pot is included or should be added.
• Whether a teacher-demonstration model such as the Ganong’s potometer is also required.
• The delivery location and any tender or purchase-order format you use.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of this Potometer Apparatus. The potometer is produced at the company’s own licensed factory at Saha, Ambala, Haryana, India, and goes factory-direct to schools, colleges, dealers and importers, so there is no trader between the buyer and the maker.

If a capillary tube or syringe needs replacing after years of class use, ask us — spares and repeat orders are dealt with by the manufacturer itself. Background on the business is on our company profile.

• Potometer Apparatus (Ganong’s) — a Ganong-pattern alternative suited to teacher demonstrations of absorption and transpiration rates.
• Stopwatch, Digital — for timing the bubble’s movement consistently in each condition.
• Digital Hygrometer - Thermometer — records humidity and temperature around the shoot during each trial.
• Glass Beaker — holds water while shoots are cut and kept fresh before fitting.
• Photosynthesis Apparatus — a companion plant physiology practical for the same unit of study.

Frequently Asked Questions

What does the Potometer Apparatus measure?
The Potometer Apparatus measures how quickly a small plant shoot takes up water, shown by a bubble moving along the capillary tube. Since most absorbed water is lost from the leaves, this rate is used in class as a practical measure of transpiration.

Why is the Potometer Apparatus described as low-breakage?
The Potometer Apparatus has only one glass part, the capillary tube, and it is mounted on a strong backing plate. That leaves far less fragile glassware to damage in student hands, although the capillary itself should still be handled with care.

How is the reading reset between trials on the Potometer Apparatus?
On the Potometer Apparatus a syringe is used to bring the bubble back to zero on the scale. The shoot stays in place, so repeated readings under different conditions such as light, shade or moving air can be taken quickly.

Can the Potometer Apparatus measure anything besides transpiration?
Yes. The Potometer Apparatus can also be used to measure humidity by connecting a porous pot. Please ask on the contact page whether a porous pot is included with your order or should be added to the quotation.

Who manufactures the Potometer Apparatus?
The Potometer Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. Buyers deal directly with the maker for quotations, class sets and replacement parts.
