Even experienced chemists can become a little nervous when using a Bunsen burner. Withal, lighting and adjusting one is a uncomplicated procedure, so in that location'due south no need to stress. Start, make sure your workspace is free of potential fire hazards. In one case you're sure you've met safety protocols, connect the gas line and ignite the burner. Conform the metal collar and needle gas valve at the burner'due south base to control the flame'due south size and temperature. When you're finished, close the air and gas ports, shut off the gas main line, and put the burner away once it'southward absurd.

3. 3

   Locate safety equipment, the fire alarm, and emergency exits. Before lighting the burner, know where to get out in example of an emergency, find the emergency gas switch, and locate the fire alarm. Note safety equipment, such every bit fire extinguishers and dry powder flame retardants.^[3]

4. 4

   Handle the burner by its base of operations. Concur the Bunsen burner only by the base or by the collar at the lesser of the barrel. Later the burner is lit, the barrel itself will be also hot to handle.^[four]

   • To reinforce prophylactic habits, avert touching the barrel fifty-fifty if the burner isn't in utilize.

5. five

   Never exit a lit Bunsen burner unattended. Continue your eye on it at all times, and never leave the laboratory while it'due south lit. If you are working on something for a moment that does not require the flame, turn it down to the coolest yellow flame (known as a safe flame).^[five]

   Inspect the gas line before installing it. Make certain at that place are no cracks in the gas supply line, which is normally a thin prophylactic hose. Gently clasp the tubing along the entire length while you look closely for visible cracks. If y'all see cracks, catch a new tube or ask your lab teacher for aid.^{[half dozen]}

2. 2

   Connect the supply hose to the gas main and to the Bunsen burner. Ensure that the hose is pushed well upwardly onto the gas chief's ribs and is securely fastened to the burner. Double check to make certain you've attached the supply hose to the gas main and not to an air intake or other fixture.^[7]

   • The gas main outlet is a threaded nozzle that tapers to a signal. Expect for a characterization on the tiptop of its handle, such as "GAS" or "VAC," or ask your lab teacher for assistance.

3. 3

   Position the air ports so they're slightly open. Locate the openings at the base of the chimney and twist the neckband, or the outer metal trounce, clockwise until the holes are closed.

   • Whenever you put the burner away, you should make sure the needle gas valve is closed. That fashion, information technology'll exist set for the next person to employ.
   • You lot want the needle valve airtight when you plow on the gas supply then you'll have consummate control over how much gas yous feed the burner when you ignite it.

5. 5

   Open the gas main. Turn the handle of the gas supply chief then that it is in line, or parallel, with the outlet and supply hose. At this point, yous shouldn't hear any gas, which sounds similar hissing. If you do, plough the gas off immediately and close the burner's needle valve.^[ten]

   • After you've made sure the burner's needle gas valve is closed, you can try turning on the gas supply outlet again. If you still hear a hissing noise, consult with your instructor to endeavour and observe the problem.

6. vi

   Open up the needle valve and get your striker ready. Have your striker or a multi-purpose lighter handy before opening the burner'south valve. When y'all're ready, twist the needle valve at the bottom of the burner slightly. Stop as soon every bit you hear the hiss of gas escaping.^[11]

   • Utilise a flint striker or lighter with a long nozzle. Don't employ matches to lite a Bunsen burner.

7. 7

   Concord your striker above the height of the barrel and ignite it. Concord the striker or lighter 1 to two inches (2.5 to 5.1 cm) above the barrel. Squeeze the striker to create a spark, and so pull it abroad as soon as the burner ignites.^[12]

   • If you've never used a striker earlier, practice making sparks until you're comfortable using it.

   Use the needle valve to control the flame's size. The needle valve on the bottom of the Bunsen burner adjusts the gas flow rate, which determines the pinnacle of the flame. More gas will create a larger flame, and less gas gives you a smaller flame. Open or close the needle valve until you've adjusted your flame to the appropriate size for your task.^[13]

2. 2

   Twist the neckband to arrange the flame's temperature. The collar controls the amount of air inbound the butt, which determines the temperature of the flame. Close the neckband so that no air enters the butt for the coolest flame, or a safety flame. When you desire to heat something, open the air ports until the flame is the correct color. The flame gets hotter as it turns blue, and is hottest when it's almost invisible.^[xiv]

   • Accommodate the air flow slowly to avoid bravado out your flame.

3. iii

   Employ a medium blueish flame for almost applications. Typically, you'll want to create a medium-sized, hot blue flame, merely the proper temperature and color depends on your task. If you're not sure, check with your lab supervisor or experiment'due south protocols.^[15]

   • Remember to close the air ports to create a cooler flame when you're not heating something, and never leave the lit burner unattended.^[sixteen]

• Question

  Why tin can't I impact it when information technology's on?

  

  Yous will get burned by the flame unless it is not getting supplied oxygen. This is described equally the safety flame.

• Question

  What is the pipe portion of the Bunsen burner called?

  

  Michael Li

  Customs Answer

  It is oftentimes referred as the "burner tube," but some might refer it every bit the "barrel."

• Question

  Why should I close the air hole when I am not heating something with a Bunsen Burner?

• Question

  What color should a Bunsen burner flame be?

  

  Safe flame, when it is deprived of oxygen from the air lock, is a xanthous-orange colour. When roaring, you should have a run across-through flame with the odd flicker of orange or blue.
