Definition
Several laboratory chemistry procedures need a Bunsen Burner and a specific gas stove. It may be used for high-temperature sterilization, combustion, and heating. A burner may employ a variety of gases, including butane, gas, methane, or a combination of these. The resulting flame is hotter than one made from only air and gas. The German scientist Robert Bunsen is credited with its introduction in the middle of the nineteenth century.
Bunsen Burner Parts
Typically, a Bunsen Burner Parts whole body is manufactured from metal, and it is attached to a stable base that rests on the bench. Rubber tubing connects the burner’s primary gas entrance at its base to a nozzle for gas on a lab table. Turning on the lab gas nozzle causes gas to rise from the burner’s base and into the flame. Air is introduced into the gas mixture from the sides via tiny pores in the vertical tube above the gas entrance. The gas only burns at the very tip of the burner after being lit at the top using a lighter or match.

Bunsen Burner Parts
The different parts of a Bunsen burner include:
- Barrel: vertical metal tube connected to base
- Collar: connects the barrel to the base
- Air holes: present in the collar and allow adjustable flow of air into the gas mixture in the barrel
- Gas intake: connects to the gas source at the lab bench via a rubber hose
- Gas valve: regulates flow of gas
- Stand/base: used to set the burner on the bench
Bunsen Burner Functions
Before, during, and after using a Bunsen burner, there are a few items that must be remembered. If these safety measures aren’t taken, the operator and anybody else in the lab might be in danger of a serious fire.
To get ready to use a Bunsen burner:
- Make sure you’re using the right tubing and that any damaged tools are promptly replaced.
- Inform everyone working in the lab that we will be using a burner.
- Put away any flammable items and tuck up long hair or loose garments.
- Starting a Bunsen burner on fire:
- Prepare a sparker or lighter. Never light a match.
- Make sure the needle valve or collar is fully closed.
- Turn the needle valve a half turn to the open position before igniting.
- The collar may be adjusted to control airflow and produce a perfect blue flame.
- While using a Bunsen burner, one must:
- Don’t ever walk away from it.
- If the flame goes out while the burner is still on, turn off the gas at the valve.
- In the wake of a Bunsen burner session:
- Turn the gas off completely by closing the valve.
- Please wait until it has cooled down before touching it.
- If necessary, turn off the lab’s main gas valve.
When adding fuel, the first thing is that air will enter the barrel when the air hole opens. If the air holes close, a yellow wave-like flame called the coldest flame glow will appear.
No soot or smoke was produced in the flame. Bunsen burners are easy to use, so you should always be alert to laboratory safety rules and regulations to avoid danger. Students should quickly be referred to for emergency treatment in any dangerous or accidental situation.

The Bunsen burner produces two types of flames, namely the luminous flame and the non-luminous flame. The glowing flame is the coldest part of the flame, while the non-luminous flame is the hottest part of the flame.
