Use of a Bunsen Burner - WebAssign
Use of a Bunsen Burner A Bunsen Burner is a gas-fueled device used for heating or burning materials in labor- atories. It produces an open flame which can be very hot. Bunsen burners provide safe, efficient heat when used properly. The key to proper operation of a Bunsen Burner is controlling the gas and air supply to the Burner . The Bunsen Burner is connected to a gas supply on the bench by means of a rubber tube. As shown in Figure 1, the valve on the bench is open if the handle aligns with the gas nozzle, and closed when the handle is perpendicular to the nozzle. It should be fully open when operating the Bunsen Burner . IF THE Burner IS NOT LIT, THE. BENCH VALVE SHOULD BE CLOSED. The gas supply to the Burner is regulated by a needle valve, which is opened and closed by a dial below the base of the Burner , as shown in Figure 2. This should be open about a full turn when you intend to light the Burner .
