Abstract In view of the use of a large quantity of liquid,low utilization rate of reaction liquid,and poor safety of the Kipp's apparatus,this paper designed a new gas generator,which was composed of a liquid storage cup,a flow regulator,an exhaust pipe and a reaction vessel. Liquid reactants were added into the reaction vessel by the flow regulator and reacted completely with solid reagents,and discharge liquids contained very few liquid reactants. Therefore,the amount of liquid reactants required was greatly reduced. The experimental results showed that the new device had the advantages of little dosage of liquid reactants,high efficiency,good safety performance,and convenient operation. Meanwhile,it had the characteristic of the immediate use just like Kipp's apparatus. It could be effectively applied in chemical experiment teaching.
