This Bromine Diffusion Kit enables educators and students to observe gas diffusion and molecular motion in real time. Bromine vapor, with its distinct color and volatility, diffuses through air in a sealed system, illustrating principles of kinetic theory and molecular collisions. The apparatus is designed with safety in mind due to bromine’s toxicity.
Features
Purpose: Demonstrates kinetic theory of gases via bromine vapor diffusion - Components Include: - Two thick-walled glass diffusion tubes (approx. 430 mm × 50 mm) - Side tube near one end for vapor introduction - Two large-bore 8 mm stopcocks with rubber bungs - Six glass cap tubes - Six bored rubber stoppers - Twelve rubber tubing pieces (125 mm × 12 mm ID) - Two plastic adapters (8 mm compatibility) - One small cleaning brush - One pack of Vaseline - Safety Note: Supplied without bromine; bromine must be handled with extreme care and only by trained personnel
