Open Flame Alternatives

Open flames are not recommended for use in the lab. Open flames generate aerosols, which may contain pathogens. The heat emitted by constant flame disrupts airflow in biosafety cabinets and clean benches and may damage the filters in these units. Open flames present a fire hazard in the lab.

Alternatives to using an open flame:

• shielded electric incinerator

• hot bead sterilizer

• disposable loops and plastic needles

• autoclaved utensils and equipment

If a flame is absolutely necessary, use a Bunsen burner that provides the flame on demand.
