Smoke Cell
Product Code : LSK-CL-10238
Smoke Cell (SKU LSK-CL-10238) is an illuminated chamber that attaches to a microscope so students can watch smoke particles jiggle at random, the effect known as Brownian motion. It gives direct visual evidence that the particles of a gas are moving and is used in secondary science and senior physics and chemistry. As a school laboratory equipment supplier in India, Science Lab Supplies dispatches it from Ambala to schools, colleges, contractors and distributors.
Specifications
The smoke cell's full specification follows in the table. In short, it is a 90 x 46 x 25 mm box with a plastic lid and flanges that attach it to standard microscopes; inside, a 12 V, 3 W festoon bulb shines through a cylindrical condensing lens into the cell, with the light preset to focus at the correct height.

Applications and Experiments for the Smoke Cell
The cell is used for one classic observation: under the microscope, bright specks of smoke move in short, random zigzags because invisible air molecules keep striking them. Students link this to the kinetic model of matter and to the idea that particles in a gas are in constant motion.
- Class 9 science (NCERT): evidence that particles of matter are continuously moving.
- Class 11 physics and chemistry: Brownian motion within kinetic theory of gases.
- B.Sc. physics: qualitative study of Brownian motion before quantitative work.
Fill the cell with a little smoke from the squeeze bottle, close the lid, switch on the lamp and focus the microscope on the bright points of light.
Standard Scope of Supply
The box holds the smoke cell, the cylindrical condensing lens and the 12 V, 3 W festoon bulb, and the set also includes a squeeze-bottle smoke generator and detailed instructions. The microscope and a 12 V supply for the bulb are not included; both can be added to the same quotation.
Packing, MOQ and Lead Time
You may request a price for one smoke cell or for a set per microscope in a physics or chemistry lab. The Science Lab Supplies quotation states the packing, delivery time and price for that number; microscopes and power supplies can be quoted at the same time.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. A quotation for smoke cells can be started from the contact page, assembled in the enquiry cart next to microscopes, or handled as a bid via the lab tender page.
Frequently Asked Questions
What does a smoke cell show?
It shows Brownian motion: the random, jerky movement of smoke particles caused by collisions with air molecules. This is visible evidence for the kinetic theory of gases.
Does it fit an ordinary school microscope?
The box has flanges designed for easy attachment to standard microscopes, and its light has been preset to focus at the correct height for viewing the smoke particles.
Who supplies the Smoke Cell?
The cell comes from Science Lab Supplies in Ambala, India, which can quote it on one list with microscopes, power supplies and kinetic-theory apparatus for schools, colleges and tender contractors.
What is needed to use it?
A microscope and a 12 V supply for the bulb, for example the AC/DC Laboratory Power Supply, whose DC steps include 12 V, or the Solar Power Supply Eliminator (2–12V). The smoke generator and instructions come with the set.
