Bunsen Burners in the Lab: Types, Safety, and Best Practices

The Bunsen burner is one of the most iconic pieces of laboratory equipment, still widely used in schools, universities, and industry labs across Australia. Its simplicity, reliability, and versatility make it an essential heating tool for experiments ranging from sterilisation to flame testing. Choosing the right type of burner and following safety best practices ensures both effective results and a safe lab environment.

Types of Bunsen burners include natural gas burners, LPG burners, and adjustable flame models. Natural gas burners are the most common in teaching and research labs, providing a clean, controllable flame for heating and sterilisation. LPG burners are used where piped gas is unavailable, offering flexibility and portability. Adjustable flame burners allow precise control of flame intensity and are favoured in advanced chemistry and microbiology applications.

Safety is critical when working with open flames. Burners should always be placed on heatproof mats, with combustible materials kept clear of the work area. Proper lighting techniques — using a spark lighter rather than matches — reduce the risk of accidents. Ventilation is also essential to avoid gas buildup. For schools, safety training and supervision are particularly important when students are handling burners.

LabChoice Australia supplies a full range of Bunsen burners designed for education, research, and industrial applications. With adjustable flame options, durable construction, and compliance with laboratory safety standards, they provide both reliability and peace of mind.
