Glass Farmer's Potometer Manufacturer,Supplier and Exporter in India

Product Code : SCL-BP-12561

The Glass Farmer'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

Glass Farmer's Potometer from School Equipments India is intended for supervised biology experiments on transpiration, water absorption, xylem transport, and plant-water relations. It helps students observe capillary-bubble movement and compare how environmental conditions affect the rate of water uptake by a leafy shoot.

A typical Farmer's potometer uses a central reservoir, three-hole stopper, graduated capillary tube, funnel with stopcock, and short glass tubing for holding the plant shoot. Exact glass type, reservoir size, capillary graduation, stopcock material, tubing material, stand/clamp inclusion, and certificate availability should be confirmed before publication or quotation.

Key Features

• Transpiration experiment apparatus: used to study water uptake by a cut leafy shoot.
• Glass construction: product name indicates glass; exact glass type must be verified from the final datasheet.
• Capillary observation method: supports visible air-bubble movement during water-uptake measurement.
• Reservoir and funnel design: typical Farmer's potometer layout includes a water reservoir and funnel with stopcock.
• Botany teaching value: supports lessons on transpiration, stomata, xylem transport, and environmental variables.
• Classroom practical use: suitable for supervised demonstrations, observation tables, and graph-based analysis.
• Specification-safe procurement: capacity, graduation, glass type, accessories, and standards should be confirmed before order.

How to Use the Glass Farmer's Potometer

1. Inspect the glass reservoir, capillary tube, funnel, stopcock, stopper, and shoot connection for cracks or leaks.
2. Fill the apparatus completely with water and remove unintended trapped air.
3. Cut a fresh leafy shoot under water to reduce air entering the xylem.
4. Fit the shoot into the tubing or glass connection and make the joint airtight.
5. Introduce a visible air bubble into the capillary tube as directed by the practical method.
6. Record the starting bubble position and begin timing.
7. Measure bubble movement over a fixed time interval.
8. Repeat under controlled conditions and compare the rate of water uptake.

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

Frequently Asked Questions

What is a Glass Farmer's Potometer used for?

A Glass Farmer's Potometer is used to measure water uptake by a cut leafy shoot as an indirect estimate of transpiration rate. It is commonly used in botany and plant-physiology practicals.

How does Farmer's Potometer measure transpiration?

As the leafy shoot takes up water, an air bubble moves through the capillary tube. The bubble displacement over time is used to compare water uptake under controlled conditions.

What parts are included in a Farmer's Potometer?

A typical Farmer's potometer includes a central reservoir, stopper, graduated capillary tube, funnel with stopcock, and plant-shoot connection. Final supplied parts should be confirmed before ordering.

Is the potometer made of borosilicate glass?

The product name confirms glass, but the exact glass type is not verified here. Borosilicate glass should be claimed only after checking the final datasheet, product label, or quotation.

Does the kit 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 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.
