Smoke Cell
Product Code : LSK-CL-10238
Smoke Cell (SKU LSK-CL-10238) is a small illuminated chamber that fits onto 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. Science Lab Supplies, a school laboratory equipment supplier in India, delivers it from Ambala to schools, colleges, contractors and distributors.
Specifications
The unit is a 90 x 46 x 25 mm box with a plastic lid and flanges that clip it to standard microscopes. Inside, a 12V 3W festoon bulb shines through a cylindrical condensing lens into the smoke cell, and the optics come preset to focus the light 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 12V 3W 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 part of this listing.
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. Reach the team via the contact page, collect items in the enquiry cart, or check the lab tender page for tender supply.
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 to attach to standard microscopes, and the light is preset to the correct height, so it sits on the stage of a typical student microscope.
Who supplies the Smoke Cell?
Science Lab Supplies supplies this cell from Ambala, India together with microscopes and other 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. The smoke generator and instructions come with the set, so no other consumables are needed for the observation.
Related Kinetic Theory and Microscopy Equipment
The smoke cell depends on a microscope and a low-voltage supply, and it pairs well with a model that shows molecular motion on a larger scale. These four items from the range complete a Brownian motion station.
- Compound Biological Microscope — the instrument the cell clips onto.
- Digital Microscope — lets a whole class watch the particles on screen.
- Kinetic Theory Model — a large-scale model of moving gas particles.
- Universal Power Supply or Power Driver — a low-voltage source for the lamp.
