Kipps Apparatus complete set 1000ml India

Kipps apparatus, also called Kipps generator, is an apparatus designed for preparation of small volumes of gases. It is widely used in chemical laboratories and for demonstrations in schools. Kipps Apparatus made of Polyethylene has three main portions. The top portion is fitted with a thistle funnel and a bulb structure through which dilute acid can be poured which reacts with a metal sulphide in the base of the apparatus. H S gas then evolved collects in the middle dome from where it can be released through a leakproof stopcock fitted with a self-lubricating PTFE plug. The base is provided with a residual outlet fitted with a cap for easy cleaning.

The apparatus is made of three vertically stacked cylinders, roughly resembling a snowman. The solid material (e.g., iron sulfide) is placed into the middle cylinder, the acid is put into the top cylinder. A tube extends from the top cylinder into the bottom cylinder. The middle cylinder has a tube with a stopcock attached, which is used to draw off the evolved gas. When the stopcock is closed, the pressure of the gas in the middle cylinder rises and expels the acid back into the top cylinder, until it is not in contact with the solid material anymore, and the chemical reaction stops.
