Note: DIN burners cannot be turned off completely in accordance with standard 30665. Therefore, a small flame continues to burn even when the gas tap or needle valve is closed. For safety reasons, the user is forced to shut off the gas supply for the laboratory burners at the central, stationary shut-off prescribed in the laboratory.
