1. Get a Bunsen burner and a piece of rubber tubing for Bunsen burners. Check for any cracks or damage on the rubber tubing. Get a new piece of tubing if yours is damaged. Attach one end of the tubing to the gas source on the laboratory bench and the other end to the gas inlet on the Bunsen burner. 2.
Bunsen Burner Natural Gas
The Bunsen burner was designed by Robert W. E. Bunsen in Germany more than 150 years back. By controlling the mixing of aerial oxygen with the fuel (hydrocarbons, nitrogen oxide, biogas, etc.) or fuel mixture, Bunsen burners can produce either oxidizing or reducing flames. The temperature of the Bunsen burner flame is different in different zones. This burner is mandatory for qualitatively.

The rubber tube should be connected to a gas tap. When using a Bunsen burner on a surface that is not heat resistant, place a heating pad underneath it. A cover for the air hole should be placed on the collar. 3 cm above the top of the barrel, light a match and hold it there. In the "on" position, turn the gas faucet.
Bunsen Burner Definition, Principle, Parts, Functions
A Bunsen burner is one of the most common pieces of equipment in the laboratory, and many scientists use it in their work. It is a special burner, which uses flammable natural gases such as methane, or petroleum gases such as propane, to burn and works similarly to a gas stove. However, it has an air supply controlled by an adjustable hole.
Bunsen burner แปลว่า คือ หมายถึง ตัวอย่าง การใช้ Dr. Krok
A Bunsen burner, named after Robert Bunsen, is a kind of ambient air gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion.. The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture.Combustion temperature achieved depends in part on the adiabatic flame.

Meker Burner merupakan pembakan bunsen yang didesain untuk menghasilkan suhu yang sangat panas dan stabil. Pada saat api dinyalakan, kisi-kisi di bagian atas memberikan nyala api yang jauh lebih pendek dan lebih kuat (± 1180 °C) dan lebih tenang tetapi dengan konsumsi gas yang lebih boros.
Bunsen Burner General Hardware Utest Material Testing Equipment
Bunsen burner, device for combining a flammable gas with controlled amounts of air before ignition; it produces a hotter flame than would be possible using the ambient air and gas alone. Named for Robert Bunsen, the German chemist who introduced it in 1855 (from a design by Peter Desdega, who likely modified an earlier design by Michael Faraday), the Bunsen burner was the forerunner of the gas.

The Bunsen burner uses the combustion of methane (also called natural gas) and oxygen according to Equation 1 to produce heat. If enough oxygen is available, roughly two moles of oxygen for each mole of methane, then complete combustion will occur and maximum heat (flame) will be produced. If the amount of oxygen

To light a burner; Bunsen burners are generally used to rapidly heat high-boiling liquids with low flammability (such as water). Safety note: It is important to know that they can reach temperatures of approximately \(1500^\text{o} \text{C}\),\(^5\) and can easily ignite most organic compounds. If an apparatus is improperly set up, or if there is a small gap that allows organic vapors to.

Bunsen burners are also often used for sterilising other instruments because the flame creates an updraft that helps to prevent bacteria from settling on nearby containers. Other uses include heating chemicals in test tubes and beakers, or combusting other materials. Almost any experiment which requires a heat source could use a Bunsen burner.

A Bunsen burner is a piece of equipment used for the general purpose of heating substances. When connected to a gas line and lit with either a striker or a match, Bunsen burners generate a controllable, open flame that is hot enough for most classroom experimental procedures. The flame produced consists of a visible outer cone and inner cone.
