SMOKE CELL

For demonstrating Brownian motion. A short cylindrical cell, closed by a cover glass, is held vertically in an opaque channel, 90 x 90 x 30 mm. IIIumination is by an integral filament bulb and cylindrical glass lens. The cell enables Brownian motion to be observed for at least 15 minutes after charging the cell with smoke / fitted 4 mm socket terminals for connection 12 V supply.
