The purpose is the introduce the fuel gas in the burner.
I prefer a number-two pencil and sheet of fine copier paper when drawing pictures of laboratory equipment. But the technique is pretty simple: you either get a Bunsen burner from the lab, or download a photo of one from the Internet, and sketch it.
BarrelThe barrel of a Bunsen burner is a metal tube that screws onto the base of the burner, with small holes called air intake openings in the bottom that let air into the barrel. As outlined by the Eastern Illinois University's Equipment Guide when a Bunsen burner is operational, natural gas draws air into the barrel as it passes the air intake openings--the mixture of air and gas is ignited at the top end of the barrel.CollarThe collar of a Bunsen burner is located around the air holes on the bottom of the barrel. The collar's function is to increase or decrease the amount of air going into the barrel; this is done through a screw mechanism. The typical action is three full counterclockwise turns for the maximum air intake and clockwise turns to close, or lower, the air intake.Gas Flow ValveThe gas flow valve of a Bunsen burner is attached to the base, directly underneath where the barrel screws on. The gas flow valve is responsible for letting gas into the barrel and can be adjusted in a similar manner to the collar--three counterclockwise turns for full gas, and clockwise turns for lesser gas or to turn the burner off completely.Gas Intake TubeThe gas intake tube is attached to the base and extends to the gas flow valve. The intake tube is corrugated and tapers at the end. This is so that an air-tight fit can be achieved with the gas pipe that is attached to the gas intake tube, making sure that there is no leakage of gas.BaseTypically, the base of a Bunsen burner is hexagonal (has six sides) and is usually 1 inch or less wide. A base has upward-slanting metal fixings on two sides that connect just above the gas flow valve and just below the gas intake tube. The base is designed to be heavy and sturdy to minimize incidents of Bunsen burners tipping over.
The gas enters the Bunsen burner through a tube connected to a gas source, such as a gas line or a gas tank. The gas flows through the tube and into the burner where it mixes with air before being ignited.
A loop is sterilized by inserting it into a Bunsen burner flame until it is red hot. 1) This will incinerate any contaminating organisms that may be present. 2) This will ensure that viable cells are transferred.
A Bunsen burner typically consists of a base, gas inlet tube, air control collar, barrel, and burner tip. The base is used to stabilize the burner, the gas inlet tube connects to the gas source, the air control collar adjusts the air flow, the barrel houses the flame, and the burner tip is where the gas mixes with air and ignites.
The gas intake tube on a Bunsen burner allows for the flow of gas into the burner where it mixes with air to create a controlled flame. Adjusting the flow rate of gas through the intake tube regulates the size and intensity of the flame produced.

The Bunsen burner goes under a thin, fireproof chemistry table.

No, the Bunsen burner is adjusted by turning the gas valve to control the flow of gas and adjusting the air intake holes on the burner tube to control the air/gas mixture. The collar is typically used to adjust the size and shape of the flame.
a bunsen is a type of burner used to heat test tube
When heating a test tube over a Bunsen burner, you typically use heat-resistant gloves to handle the test tube, a test tube holder to hold the test tube, and a Bunsen burner for heating. It's also important to have a heat-resistant mat or pad to place the test tube on while heating.
To adjust the flame on a Bunsen burner, you can turn the gas valve to increase or decrease the flow of gas. Moving the collar on the burner tube will control the air intake, which can change the type of flame produced. Combine these adjustments to achieve the desired flame size and type.

The gas enters the Bunsen burner through a tube connected to a gas source, such as a gas line or a gas tank. The gas flows through the tube and into the burner where it mixes with air before being ignited.
The Bunsen burner was designed by Robert Bunsen in collaboration with his laboratory assistant, Peter Desaga. It includes two key elements: a vertical metal tube through which gas can flow and a rotating collar to control the air intake, allowing for more precise control of the flame.
