Bromine Diffusion Kit

For demonstrating the kinetic theory of gases by means of bromine vapours. Bromine molecules, initially moving at very high velocities with their unrestrained movement within a vacuum, immediately gets stalled when diffusing into air due to their elastic collisions with the air molecules. Designed with safety of the user in mind due to the toxicity of bromine. Comprises two sturdy, thick walled glass diffusion tubes about 430x50mm (height x diameter) with a small side tube near one end, two large bore 8mm stop-cocks with rubber bungs, six glass cap tubes, six bored rubber stoppers, twelve pieces of rubber tubing 125x12mm (length x inner diameter), two plastic adapters to adapt tubes to 8mm, one small brush for cleaning tap and one pack of Vaseline.
