Laboratory H-Type Potometer Manufacturer,Supplier and Exporter in India

Product Code : SCL-BP-12560

The Laboratory H-Type Potometer is a plant-physiology apparatus used for measuring water uptake by a leafy shoot as an indirect indicator 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 H-Type Potometer from School Equipments India is designed for individual student use in biology and plant-physiology experiments. The apparatus allows learners to observe how a cut shoot takes up water and how an air bubble moves through a capillary tube during transpiration studies.

The verified School Equipments India listing specifies a wide glass tube reservoir measuring 160 mm × 20 mm, an 8 mm diameter side arm, a 140 mm capillary tube, and a 1 mm capillary bore. Exact glass composition, tubing material, scale graduation interval, packing list, and certificate availability should be confirmed before publication or tender submission.

Key Features

• H-type configuration: supports individual student observation of water uptake and transpiration.
• 160 mm × 20 mm reservoir: verified wide glass tube reservoir for the listed model.
• 8 mm side arm: allows the cut shoot to be connected through suitable tubing.
• 140 mm capillary tube: provides the observation path for air-bubble movement.
• 1 mm capillary bore: supports visible movement during comparative water-uptake experiments.
• Plant physiology focus: useful for teaching transpiration, xylem water movement, and environmental effects.
• Student practical format: suitable for supervised classroom experiments and observation records.

• Supporting tender-based procurement for biology laboratory apparatus

How to Use the Laboratory H-Type Potometer

1. Inspect the glass reservoir, side arm, and capillary tube for cracks, leaks, or blocked passages.
2. Fill the potometer completely with water and remove unintended trapped air.
3. Cut a healthy leafy shoot under water to reduce air entering the xylem.
4. Attach the cut shoot to the side arm using suitable tubing and make the joint airtight.
5. Introduce one visible air bubble into the capillary tube as directed by the practical method.
6. Record the starting position of the bubble and begin timing.
7. Measure bubble displacement over a fixed time interval.
8. Repeat under controlled conditions and compare the calculated water uptake rate.

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

Care & Maintenance

• Rinse the glass tube and capillary after use to remove dye, plant residue, or biological material.
• Clear the capillary gently if blocked; do not push hard wires through the bore.
• Dry the apparatus completely before storage to reduce residue and biological growth.
• Store in a protected cabinet or padded box to prevent capillary breakage and side-arm damage.

Frequently Asked Questions

What is a Laboratory H-Type Potometer used for?

A Laboratory H-Type Potometer is used to measure water uptake by a leafy shoot as an indirect indicator of transpiration rate. It supports plant physiology practicals in school and college biology labs.

What is the reservoir size of this H-Type Potometer?

The verified School Equipments India listing specifies a reservoir dimension of 160 mm × 20 mm.

What is the capillary tube size?

The verified listing specifies a 140 mm long capillary tube with a 1 mm capillary bore.

How does an H-Type Potometer measure transpiration?

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

Does the potometer include the plant shoot?

Plant material is not confirmed. A fresh leafy shoot is normally required for the experiment, but inclusion should be checked before ordering.

Is it suitable for school biology labs?

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