Visualising Osmosis & Diffusion Investigation Manufacturer,Supplier and Exporter in India

Visualising Osmosis & Diffusion Investigation (Product Code: SLE/ECB/19) is a class investigation used to demonstrate selective permeability with coloured solutions in school biology lessons on the cell membrane. Sized for a class of 40 students, it pairs a model cell with a mixture of special dye solutions, so learners watch the membrane let one dye pass while the other stays inside. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as an osmosis experiment kit for school laboratories.

Key Details

What Is the Osmosis & Diffusion Investigation Used For?

The investigation is built around a prediction: once the model cell is placed in the dye mixture, which colour will end up where? As the experiment runs, the membrane lets one dye through and holds the other back, and the colour change inside and outside the cell gives students clear evidence that membranes are selective rather than simply porous. Teachers then use the result to explain how smaller molecules move by diffusion down a concentration gradient, why larger molecules are retained, and how water moves by osmosis through the same semipermeable membrane until equilibrium is approached.

Because it needs no living material, the activity is predictable enough for timed practical lessons and suits younger classes under normal laboratory supervision. It fits well after a simple osmosis demonstration and before work on root hair cells, the small intestine or kidney function, and it gives every group in a biology lab setup the same clear result. Keep the dye solutions capped, label any mixtures prepared in advance and wear gloves if students handle the solutions directly.

Supplier

This investigation is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India.

Frequently Asked Questions

How many students is the Visualising Osmosis & Diffusion Investigation designed for?
The Visualising Osmosis & Diffusion Investigation is sized for a class of 40 students. If you teach several sections or are equipping more than one school, give the number of classes when you enquire so the quotation covers every group.

What will students see during the osmosis and diffusion investigation?
In the Visualising Osmosis & Diffusion Investigation, the model cell's membrane lets one dye pass while the other remains within the cell. The resulting colour change is visible evidence of selective permeability and of how a cell absorbs nutrients and discharges wastes.

Does the Visualising Osmosis & Diffusion Investigation cover osmosis as well as diffusion?
Yes. Alongside diffusion of the dyes, the Visualising Osmosis & Diffusion Investigation teaches how osmosis and diffusion maintain equilibrium through the passive transport of water across the cell's semipermeable membrane, linking the demonstration to wider membrane-transport topics.

Are the dye solutions safe for school use?
Treat the dye solutions in the Visualising Osmosis & Diffusion Investigation like any laboratory solution: supervise students, use gloves and eye protection, and avoid ingestion. For safety information on the specific solutions, please contact us before the practical.

What is the shelf life of the dye solutions?
Shelf life depends on the chemical, its grade and storage conditions, so no single expiry period applies to the solutions in the Visualising Osmosis & Diffusion Investigation. Ask us for the expiry date of the batch you are quoted, and store them closed, away from heat and sunlight.

Can replacement solutions be ordered separately?
Refill availability for the Visualising Osmosis & Diffusion Investigation is not stated in the listing. Enquire with the product code SLE/ECB/19 and we will advise what can be supplied as replacement solutions for repeat classes.

Who supplies the Visualising Osmosis & Diffusion Investigation?
The Visualising Osmosis & Diffusion Investigation is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools and distributors in India and international markets. Shipping arrangements for the solutions are confirmed with the quotation.
