Bunsen Burner (Pack of 2)

A Bunsen burner is a laboratory device used to produce a controlled flame for various scientific experiments, including heating, sterilization, and combustion. Here’s how it works:

Components of a Bunsen Burner:

1. Base: The flat surface where the burner sits, providing stability.
2. Gas Inlet: Where the gas (typically methane, natural gas, or propane) enters the burner.
3. Barrel: The vertical metal tube that directs the gas upward.
4. Air Holes: Small holes near the base of the barrel, which allow air to mix with the gas for combustion.
5. Collar: A movable ring around the barrel that can open or close the air holes, controlling the amount of air entering.
6. Flame Adjuster: A knob to control the gas flow and regulate the flame’s size and intensity.

Working Principle:

1. Gas Flow: When the gas is turned on via the gas inlet, it flows up through the barrel.
2. Air Intake: Air enters through the open air holes at the base of the barrel, mixing with the gas. The amount of air is controlled by adjusting the collar.
   • More air: A hotter, more efficient flame is produced (blue flame).
   • Less air: A cooler, yellowish flame (less efficient).
3. Ignition: The gas-air mixture is ignited, typically with a match or spark. The flame burns at the top of the barrel.
4. Adjusting the Flame: By regulating the gas flow using the flame adjuster and controlling the air intake with the collar, the user can adjust the size and temperature of the flame.

• Blue Flame: A hot, clean, and efficient flame produced when there’s more air, allowing complete combustion.
• Yellow Flame: A cooler, smoky flame caused by insufficient air, producing incomplete combustion.

This setup allows precise control of heat, making the Bunsen burner versatile for laboratory experiments.
