What is Meker burner in chemistry?
noun Chemistry. a gas burner similar to the Bunsen burner but producing a hotter flame by virtue of having at its mouth a metal screen to allow a more intimate mixture of air and gas.
How does Bunsen burner work?
When the gas jet is opened, gas flows through the attached hose to the burner base. The amount of gas entering the burner tube is regulated by the needle valve at the base of the burner. If the valve is closed, gas flow is stopped. If the valve is open, gas will pass through the valve and travel up the burner tube.
How is a Bunsen burner used in chemistry?
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.
How does an electric Bunsen burner work?
The Electric Bunsen combines the advantages of a regular gas burner with the clean easy operation of our Electromantles. Radiation from the heater is directed upwards to a focal point. The Electric Bunsen is ideal for non-contact heating of test tubes, crucibles, small flasks and beakers, regardless of their shape.
How hot can a Meker burner get?
Maximum temperature is approximately 1780 °C (3236 °F). Natural gas version has a BTU range of approx. 600 to 1100.
How many types of burners are there?
There are five basic types of fuel burning home heating appliances: gas and diesel burners. ultra-low emission burners. low emission burners.
What is the use of burner in laboratory?
An indispensible tool of the lab The lab burner (sometimes referred to, and often erroneously so, as the Bunsen burner) is an indispensible tool for doing general chemistry lab work. It can be used to heat samples with high or low heat, for sterilization, to bend glass tubing or rods, or for other purposes.
What is the function of burner?
A burner is a device designed to ensure that the flame is stabilized by establishing a suitable flow field to produce the initial temperature rise. The flame is used as the source of heat to preheat the fuel/air mixture to the ignition temperature.
Why is a Bunsen burner important?
The Bunsen burner is now a very important tool in modern chemistry laboratories. It can burn a number of types of fuel, and produces a single clean and hot flame. The Bunsen burner has a valve for gas intake, and a needle valve that allows precise control of the amount of air that mixes with the fuel.
What is the use of Bunsen burner in laboratory apparatus?
A Bunsen burner, named after Robert Bunsen, is a kind of gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion.
What type of flame is preferred for laboratory work?
A non-luminous flame is preferred for lab work because it is the hottest.
What are the three types of flames on a Bunsen burner?
The three main types of Bunsen burner flames are:
- Yellow Flame. A yellow flame is also known as a safety flame because it is easy to see in a bright room.
- Blue Flame. This particular flame on a burner can get as hot as 500 degrees.
- Roaring Blue Flame. The hottest setting for Bunsen burner flames is the roaring blue flame.
How does A Meker burner work?
On a Meker burner, there is a grid at the top of the tube, which breaks the flame into many smaller flames. This produces a larger area of maximum temperature as well as an overall increase in temperature, according to an article in the Journal of Chemical Education.
What is the difference between Tirrill burner and Meker burner?
The Tirrill burner is an air and gas device much like the Bunsen, but with extra adjustments that provide for better temperature control and flame size. A Meker burner is also similar in design, but it is larger and works best for experiments that require high temperatures.

What type of gas is used in a laboratory burner?
Some laboratory burners are designed to work with natural gas (methane), while others are designed to work with liquid petroleum (also known as LP, which can be propane, butane or a mixture of the two), according to manufacturer Eisco Industrial.
