In aseptic technique, a Bunsen burner is kept lit near the agar or used to flame bottle necks; the warm air creates an updraft to prevent airborne bacterial contamination.
En la técnica aséptica, se mantiene un mechero Bunsen encendido cerca del agar o se utiliza para flamear el cuello de la botella, ya que el aire caliente crea una corriente ascendente que evita la contaminación del agar por bacterias transportadas por el aire.
