                                 and height of
                                 flame
Technique – Bunsen Burner Setup
1. Examine the Bunsen
   burner tubing for cuts and
   deep cracks.                 2. Attach the
                                   burner tubing

                                    and the needle-
                                    valve all the way

4. Turn the petcock (main gas valve handle) until it points
   straight, toward the rubber hose, and then……




         Closed                           Open
Technique – Lighting a Bunsen Burner
 ……. Hold a striker just above the barrel top, and
 squeeze the striker handle to create a spark.
Technique – Adjusting a Bunsen Burner

5. Adjust the flame. With the barrel screwed all the way in,
   the flame will be very “cool” and yellow. Adjust the flame
   with the needle-valve (fuel) and barrel (air).

  Yellow, “luminous”
        flame
    • Dirty
    • Not very hot
Technique – Adjusting a Bunsen Burner
6. With the barrel screwed all the way in, the flame will be
   very “cool” and yellow. To adjust the flame the needle-
   valve (fuel) and barrel (air) will need to be adjusted.

    Unscrew the barrel (holding the base of the barrel) until
     the flame is blue and all yellow is gone.
    Don’t add so much air that your hear a “roar.” Your
     flame should be “silent” and blue.
Technique – Adjusting a Bunsen Burner
6. With the barrel screwed all the way in, the flame will be
   very “cool” and yellow. To adjust the flame the needle-
   valve (fuel) and barrel (air) will need to be adjusted.

    The height of the flame can be raised by opening the
     needle valve (fuel).
    To most efficiently heat a sample, the tip of the inner
     blue cone should be touching the object to be heated.
Perfect Flame - Silent, Blue (Non-luminous)


 Outer cone –
 not very hot




                            The tip of the inner
Not very hot                blue cone should
                            be touching the
                            object to be heated.
Technique – Turning Off a Bunsen Burner
7. Turn the petcock (main gas valve handle) until it points
   perpendicular to the burner tubing, all the way to the left
   OR all the way to the right.




            Open


                                        CLOSED

    Never leave a lit Bunsen Burner unattended.
