Bunsen Burner, 800 TO 1200-BTU/CF, Natural Gas
The Bunsen standard lab burner has a 0.50-inch (12.7mm) aluminum mixing tube with a flame stabilizer, a circular base with a hole, and a 5/16-inch (7.9mm) OD serrated gas inlet connection. 6.125 inches (156mm) tall, Bunsen burners are a staple in the lab, a reliable heat source for many experiments. They have a gas inlet and air hole so you can adjust the air intake to control the flame temperature and size for safety and efficiency in chemical procedures. Bunsen burners can get up to 1560 ºC. The flame burns at different temperatures depending on the air mixture, more air = hotter blue flame, less air = cooler yellow flame. Incomplete combustion can produce carbon particles or soot if there’s not enough air, but adjusting the air flow will prevent this and give you complete combustion and higher flame temperatures.
with nickel-plated zinc alloy base are available for different lab applications and use 800 to 1,200btu/cf natural gas.

Design of Bunsen Burner
The sides of the metal tube have adjustable holes controlled by a collar to admit the desired amount of air. Air is drawn into the burner through these holes due to the Venturi effect when the gas flows past them. This allows for a mixture of air and gas which is then forced to the top of the tube by gas pressure. The Bunsen Burner is connected to a gas source via a hose barb and rubber tubing so it’s secure and flexible.The Bunsen Burner is designed to control both air and gas flow so you can adjust the flame to your laboratory needs. This control is crucial to get the right type and temperature of flame. This precise mixture gives you a roaring blue flame perfect for many laboratory applications. Gas flow and air is key to complete combustion and efficient heating.
This high temperature is good for many chemical reactions and heating applications. The flame is heated and can get up to 1,500 °C (2,700 °F). The hottest part of the flame is just above the tip of the primary blue cone flame where the temperature is at its highest.
Specifications for Bunsen Burner
At the base of the barrel is an air hole that aligns with a collar that acts as an air regulator. This design allows you to adjust the air flow to get complete combustion and a hot blue flame. The Bunsen burner has a hose barb at the base of the chimney so you can attach rubber tubing to a gas nozzle on the laboratory bench. This setup is secure and flexible to the gas source.
Gas flow is controlled by a gas valve on the Bunsen burner so you can precisely regulate the flame. When not in use, the burner can be set to a safety flame, usually a yellow flame, which is the default position and also used for lighting. This safety feature is important to maintain a safe laboratory environment.
Operating Principles and Safety Features of Bunsen Burner
The Bunsen burner works by combining a flammable gas (like natural gas) with amounts of air before being ignited at the top of the Bunsen burner. This starts at the air hole at the bottom of the chimney where air and gas mix. The Venturi effect (where there is a pressure difference that draws air into the air hole) helps with the mixing of oxygen with gas for combustion.
Invented by Robert Bunsen, a German chemist, in 1855, the Bunsen burner has become a standard tool in laboratory settings, known for its precise flame control and versatility. Robert Bunsen developed this reliable gas burner for his new laboratory at the University of Heidelberg.
The blue flickering flame is the hottest flame and gives you the highest temp from the burner. Adjusting the air intake can affect the flame characteristics and influence the maximum temperature. The tip of the primary flame is critical for optimal combustion and heating efficiency. Variations of the original Bunsen Burner like the Meker burner and Fisher burner have metal grids to increase turbulence and keep the flame at the top of the tube. The Fisher burner has forced air so you don’t need a secondary flame dependent on ambient air.
