A Tirrill burner is a burner that allows the gas and air supply into the burner to be adjusted individually. The Tirrill burner can be found in a bottled gas model and a natural gas model as well as an artificial gas model.
The Tirrill burner can be used for the same purposes as a Bunsen burner, such as for heating up different liquids and chemicals. These burners are most often used when experiments call for separate adjustments of the height of the flame and of the temperature of the flame. It is important to exercise caution and follow all safety procedures when operating the Tirrill burner. Note that the flame should always be a clear color.
