Kit for Experiments with Breathing
Product Code : SCL-BLE-11629
Kit for Experiments with Breathing (SKU SCL-BLE-11629) lets students simulate how the lungs work during the two phases of breathing and reveal carbon dioxide in exhaled air. The set contains a lung model, a vacuum pipette, a bottle of lime water and a three-legged stand. It is used in human-biology lessons on respiration in schools and teacher-training colleges. Orders are handled by Science Lab Supplies in Ambala, India, for schools, colleges, training institutes and distributors.
Specifications
Four items make up the breathing kit, and the table gives each one its own row: a lung model for showing inhalation and exhalation, a vacuum pipette, a bottle of lime water for the carbon dioxide test, and a three-legged stand. The two demonstrations the kit is designed for follow.

Applications and Experiments for the Breathing Kit
The kit covers two classic respiration activities: modelling how the lungs fill and empty as the chest changes volume, and showing that exhaled air turns lime water milky because it carries more carbon dioxide. It fits CBSE/NCERT Class 7 and Class 10 science and Class 11 breathing topics.
- Class 7 respiration in organisms: using the lung model to show breathing in and breathing out.
- Class 10 life processes: comparing lime water in a Test Piece glass tube before and after exhaled air is passed through it.
- Class 11 breathing and exchange of gases: linking the model to the roles of the diaphragm and rib cage.
- Preparing fresh lime water for repeat classes from Calcium Hydroxide.
Lime water is alkaline; students should not drink it or get it in their eyes, and should only breathe out through the tube, never draw liquid in.
Standard Scope of Supply
Each kit holds one lung model, one vacuum pipette, one bottle of lime water and one three-legged stand. Test tubes are not included. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
You may request a price for one kit for a class demonstration or for a kit at every group station. Each quotation from Science Lab Supplies sets out the packing, delivery time and price for that number, and lung models or respiration apparatus can be included as extra lines.
Science Lab Supplies is registered as an exporter with an Importer-Exporter Code and can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Your quantity can be sent via the contact page or the enquiry cart; for public procurement, the lab tender page explains the process.
Frequently Asked Questions
What does the breathing kit demonstrate?
It simulates the functioning of the lungs during the two phases of breathing, inhalation and exhalation, and reveals the presence of carbon dioxide in exhaled air using the lime water supplied.
How does the lime water test work?
Exhaled air is bubbled through clear lime water. Carbon dioxide reacts with it and the liquid turns milky, which shows that breathed-out air contains carbon dioxide.
Who supplies the Kit for Experiments with Breathing?
Science Lab Supplies supplies the kit from Ambala, India. Teachers, colleges, training institutes and distributors can ask for a quotation and receive it directly from the company with full order details.
Can more lime water be ordered later?
Yes. Extra lime water, or calcium hydroxide for making it fresh, can be quoted with the kit or on a later order, together with the batch expiry date for each bottle supplied.
