Description
 
An open-ended borosilicate glass tube, ideal for the 'diffusion of gases experiment'. Cotton wool soaked in concentrated ammonia solution is placed in one end of the tube and cotton wool with concentrated hydrochloric acid is placed in the other end. Both ends are stoppered with bungs, to contain the fumes. The gases diffuse along the tube from both ends, and where they meet a white ring of ammonium chloride forms.
Tube dimensions: 500 mm long x 40 mm outer diameter with 2.3mm walls and fired ends for safety.
