This document provides information about common laboratory apparatus, their functions, and how to use a Bunsen burner. It identifies 12 common pieces of apparatus such as beakers, evaporating dishes, filter funnels, and test tubes. For each it provides a brief description of its function in the laboratory. It also explains the parts and use of the Bunsen burner, identifying the gas intake and explaining that adjusting the gas valve controls the gas flow and amount of flame. More oxygen leads to a blue, controlled flame.
