Laboratory Ganong's Potometer Manufacturer,Supplier and Exporter in India

Product Code : SCL-BP-12562

The Laboratory Ganong's Potometer is a plant-physiology apparatus used for measuring water uptake by a cut leafy shoot as an indirect estimate of transpiration rate. It is suitable for school biology labs, college botany practicals, science departments, institutional tenders, distributors, and educational procurement buyers.

Product Description

Laboratory Ganong's Potometer from School Equipments India is intended for supervised biology experiments on transpiration, water absorption, xylem transport, and plant-water relations. The apparatus helps students observe air-bubble movement in a capillary tube and compare water uptake under controlled environmental conditions.

A typical Ganong's potometer uses a graduated capillary tube, plant-shoot connection, water reservoir, and stopcock arrangement. Exact reservoir capacity, glass type, capillary length, capillary bore, graduation interval, base material, stopper type, tubing, and certificate availability should be confirmed before publication, quotation, or tender submission.

Key Features

• Transpiration experiment apparatus: used to estimate transpiration by tracking water uptake in a leafy shoot.
• Graduated capillary observation: supports visible air-bubble movement for timed practical readings.
• Reservoir and stopcock arrangement: helps reset or adjust the bubble position for repeated observations.
• Plant physiology relevance: supports lessons on xylem transport, stomata, water loss, and environmental effects.
• Classroom practical use: suitable for teacher demonstrations, individual observations, and graph-based analysis.
• No electrical supply required: operates through water uptake and capillary displacement.
• Procurement-safe specification: final capacity, glass type, scale, tubing, and accessories must be confirmed before order.

How to Use the Laboratory Ganong's Potometer

1. Inspect the glass apparatus, capillary, reservoir, stopcock, and plant connection for cracks, leaks, or blockage.
2. Fill the potometer completely with water and remove unintended trapped air.
3. Cut a fresh leafy shoot under water to reduce air entry into the xylem.
4. Fit the shoot into the end tube or stopper connection and make the joint airtight.
5. Place the open capillary end in a beaker of water if required by the apparatus design.
6. Introduce one visible air bubble into the graduated capillary tube.
7. Use the reservoir and stopcock to position the bubble at the starting mark.
8. Record bubble movement over a fixed time and compare readings under controlled variables.

Safety note: Use the apparatus only under trained supervision. Handle glass carefully, avoid forcing tubing onto glass arms, and do not use cracked, chipped, blocked, or leaking components.

Care & Maintenance

• Rinse the capillary, reservoir, and plant connection after use to remove dye, sap, or plant residue.
• Clean blocked capillary sections gently without forcing wires through the bore.
• Dry all parts fully before storage to reduce biological growth and residue build-up.
• Store in a protected cabinet or padded box to prevent capillary, stopcock, and side-tube damage.

Frequently Asked Questions

What is a Laboratory Ganong's Potometer used for?

A Laboratory Ganong's Potometer is used to measure water uptake by a cut leafy shoot. This water uptake is used as an indirect estimate of transpiration rate in plant physiology practicals.

How does Ganong's Potometer measure transpiration?

As the leafy shoot takes up water, an air bubble moves along the graduated capillary tube. The distance moved over time is used to compare the rate of water uptake.

What is the purpose of the reservoir?

The reservoir supplies water to the apparatus and helps reset the air bubble towards the starting position when the stopcock or tap is opened.

Does the apparatus include a plant shoot?

Plant material is not confirmed. A fresh leafy shoot is normally required for the experiment, but inclusion should be listed only if supplied with the final kit.

Is the potometer made of borosilicate glass?

The product is treated as glass laboratory apparatus, but exact glass type is not confirmed. Borosilicate glass should be claimed only after checking the final datasheet, label, or quotation.

Is it suitable for school biology labs?

Yes. It is suitable for supervised school and college biology laboratories when teachers control setup, airtight sealing, bubble positioning, timing, and glassware safety.
