Kipp's gas generator for producing a controlled and consistent supply of gases for experiments.

• Made of high quality, heavy-duty, Borosilicate 3.3 glass
• Can be used to produce controlled amounts of common gases including hydrogen sulfide and carbon dioxide
• Three separate chambers connect together vis 24/29 ground glass joints

The Kipp's gas generator, made of high quality, heavy duty, Borosilicate 3.3 glass, is comprised of 3 chambers: a lower acid reservoir with stopper, a central bulb with tapered tube extending downwards into the reservoir, and a safety funnel. A separator prevents the solid reactant in the central bulb from falling into the reservoir. Closure of the stopcock builds up a gas pressure in the central bulb and forces the acid out away from the solid reactant, thereby halting the reaction. Opening the stopcock allows return of acid to its original level, and the reaction continues as before.
