Bunsen Burner (Pack of 2)

Bunsen Burner – Laboratory Heating Apparatus

The Bunsen Burner is a laboratory heating device used to produce a controlled gas flame for heating, combustion experiments, and suitable laboratory procedures. Supplied by Elmo Agencies, a trusted scientific manufacturer in Ambala, it is commonly used in chemistry, biology, and educational laboratories.

A Bunsen Burner mixes a gaseous fuel with air before combustion to produce a controllable flame. By adjusting the gas supply and the amount of air entering through the air openings, the user can change the flame characteristics. It is widely used where a direct and adjustable laboratory heat source is required.

Main Components

• Base: Provides stability during use.
• Gas inlet: Connects the burner to the laboratory gas supply.
• Barrel: Directs the gas-air mixture upward.
• Air holes: Allow air to enter and mix with the gas.
• Collar: Controls the amount of air entering through the openings.
• Gas control: Regulates the amount of fuel supplied to the burner.

How Does a Bunsen Burner Work?

Gas enters through the inlet and travels upward through the barrel. As the gas moves through the burner, surrounding air is drawn in through the air openings and mixes with the fuel.

The mixture is ignited at the top of the barrel. Adjusting the air supply changes the combustion conditions and therefore the appearance of the flame.

Blue Flame

With adequate air mixing, the burner generally produces a blue flame associated with more complete combustion and relatively efficient heating.

Yellow Flame

When the air supply is restricted, a yellow, luminous flame may form due to incomplete combustion and the presence of glowing soot particles. This flame is generally less suitable for clean laboratory heating.

Applications

• Heating laboratory solutions
• Heating glassware and suitable samples
• Combustion experiments
• Chemistry practicals

Safety Precautions

• Use only the fuel gas and pressure specified for the burner.
• Check connections for leaks before ignition.
• Keep flammable materials away from the flame.
• Tie back long hair and secure loose clothing.
• Never leave a lit burner unattended.
• Turn off the gas supply completely after use.
• Allow heated equipment to cool before handling.

Conclusion

The Bunsen Burner by Elmo Agencies is a practical laboratory heating apparatus for controlled flame production, heating, combustion experiments, and suitable laboratory procedures. Its adjustable gas and air supply makes it useful for chemistry practicals, educational demonstrations, and routine laboratory heating applications.
