WHAT YOU NEED TO KNOW
Nature reported that Bunsen burners fail to cleanse laboratory airspaces and surfaces effectively.
Researchers tested the burners by seeding lab air with the bacterium Gordonia rubripertincta.
Trials used Petri dishes placed near both lit and unlit Bunsen burners of differently sized dimensions.
Researchers found that Bunsen burners fail to cleanse lab airspaces and surfaces effectively, and might even increase contamination. Nature reported that scientists seeded the air above laboratory benches with the bacterium Gordonia rubripertincta during trials. Investigators opened two Petri dishes near burners of varying sizes, placing one dish beside a lit burner and another beside an unlit one.
Bacterial levels inside the dishes beside lit burners matched or exceeded the levels recorded in dishes next to unlit burners across several trials.
