Balloons
Balloons (Product Code: SCL-565/032) are latex rubber balloons of the standard kind used in school laboratories, a low-cost consumable for demonstrations that involve gases. Stretched over the mouth of a flask, a balloon catches the gas given off by a reaction and swells, so the whole class can see that a gas has formed; it also makes changes in gas volume on heating and cooling easy to follow. Science teachers keep a stock of them with the other items of a school science kit. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Typical Use
A favourite gas-production demonstration uses sodium bicarbonate and a weak acid. Place a spoonful of the powder inside a balloon, pour dilute acetic acid or vinegar into a conical flask, and stretch the balloon over the neck with the powder hanging to one side. Lifting the balloon tips the powder into the acid; carbon dioxide is released and the balloon inflates. Groups can compare how far their balloons swell with different amounts of reactant, which leads naturally into a discussion of how much gas a reaction produces.
For the gas laws, fit a balloon over an empty flask, warm the flask gently in a water bath and then cool it: the balloon rises as the air expands and falls back as it contracts, a simple qualitative lead-in before measured work with a Charles law apparatus. Stretch each balloon a few times before use so it inflates easily, and secure it with a rubber band if the fit is loose. Because the balloons are latex, check whether anyone in the class has a latex allergy, and store unused stock away from heat and sunlight, which make latex brittle.
Supplier
Jain Scientific Equipments Private Limited, operating as ScienceLab in Ambala, Haryana, supplies the consumables needed to run school practicals, balloons included, to customers in India and international markets. Company details are on the ScienceLab profile.
Related Chemistry Lab Equipment
For the gas-production and gas-law demonstrations described above, order these alongside the balloons:
- Sodium Bicarbonate — the solid that releases carbon dioxide to inflate the balloon.
- Glacial Acetic Acid — diluted by the teacher to make the acid for the bicarbonate reaction.
- Conical Flask — the vessel the balloon is stretched over.
- Rubber Bands (Good Quality) — to hold the balloon neck tight on the flask.
- Boyle’s Law – Simple Type — for measured gas-law experiments after the balloon demonstrations.

Frequently Asked Questions
What are the balloons made of?
Rubber, with a latex composition.
What sizes and colours are supplied?
These are not listed. Ask us through the contact page and we will tell you what is available.
Are they suitable for someone with a latex allergy?
No. They are latex rubber, so plan a different demonstration or keep them away from anyone with that allergy.
How many come in a pack?
Pack quantity is not stated. Tell us how many balloons you need for your classes and we will quote for that number.
How should spare balloons be stored?
In a cool, dry, dark cupboard. Heat and sunlight age latex and make it split more easily.
Do you supply schools in bulk and overseas buyers?
Yes. We supply institutions and dealers in India and international markets, and balloons can be quoted with the rest of your consumables.
