摘要：A simple and cost-effective bench-top gas generator for its use in the laboratory classes is designed and fabricated. The set-up is meant for generation of hydrogen sulfide gas and is in use by the students at the chemistry laboratory of our college for the past eight years. However, other gases like carbon dioxide, hydrogen and acetylene can also be produced using the same set-up. This article describes the design and fabrication of the bench-top set up with special reference to generation of hydrogen sulfide gas. The new set-up is easy to use and requires few chemicals.
