A gas bottle is used in a lab for collecting various types of gases for experiments and we are here supplying the head for gas bottles that will close the opening of the gas bottle and will help in performing the further experiment. It is like cap for the bottle that will help in transferring fumes of the gas into other bottles or any other apparatus based on experimentation. The head for glass bottle is important from safety point of view as it will stop the gas from being leaked out of the bottle.
