Founded by the German scientist Robert Bunsen, the Bunsen burner is one of the most common objects that you will find in any laboratory. The Bunsen Burner has many different parts that it is made up of. The parts that it is made of include the barrel, collar, gas flow valve, gas intake valve, and the base. The barrel is metal tube that will screw onto the base of the burner. It contains small holes called air intake openings at the bottom that allow airflow into the barrel. What the barrel’s main function is, is to ignite the mixture of air and gas. The way that this works is that natural gas draws air into the barrel as it flows through the air intake openings, the mixture is then ignited at the top end of the barrel. The collar of the burner is located around the air holes on the bottom of the barrel. What the collar does is it increases or decreases the amount of air that will go into the barrel. This is completed through a screw mechanism. The amount of times you turn the collar, will determine the amount of air take, thus allowing you to lower or even close the air intake. The gas flow valve is attached to the base right underneath where the barrel screws on. The job of the gas flow valve is to let gas go into the barrel. It can be adjusted in a similar way as the collar, threw counterclockwise turns for a full amount of gas, and clockwise turns to obtain less gas, or turn the barrel off completely. Along with those parts the burner also contains a gas intake tube. This tube is attached to the base and extends to the gas flow valve. The tube and corrugate and tapers at the end. It is a very air-tight tube so that the none of the gas will leak. The base of the burner usually has 6 sides and is 1 inch or so wide. The base will have a upward-slanting metal fixings on both sides that connect just above the gas flow valve and a little below the gas intake tube. The base is specially designed to be heavy and sturdy to maintain balance and...
