Smoke Cell
Product Code : JA-LE-6942
The Smoke Cell (SKU JA-LE-6942) is a small apparatus for watching Brownian motion, the random jiggling of smoke particles as they are struck by air molecules. The smoke cell for Brownian motion clips to a standard microscope by its flanges; a 12 V festoon bulb and cylindrical condensing lens light the particles from the side, and the light is preset to focus at the correct height. It comes with a squeeze-bottle smoke generator and instructions. It is made by JaincoLab.
Specifications
The smoke cell measures 90 x 46 x 20 mm and contains the cell, a cylindrical condensing lens and a 12 V, 3 W festoon bulb, with the light preset to focus at the correct height.

Teaching with the smoke cell for Brownian motion
Seeing bright specks of smoke dart about at random gives students direct evidence that air is made of moving particles, which underpins the kinetic theory taught in physics and chemistry.
- Observing Brownian motion under a school microscope
- Evidence for the particle model and kinetic theory
- Physics and chemistry practicals in secondary schools
- Demonstrations in teacher-training laboratories
