Ray Export supplies laboratory gas burners for chemistry practicals in Bunsen, Meker, Teclu, fishtail and micro formats, together with a flame spreader for round-wick burners. The range carries catalogue numbers B-0001 to B-0010. The items differ mainly in flame temperature, flame shape and how the gas is controlled: the Teclu and Meker types are described as giving a hotter flame than a plain Bunsen burner, while the fishtail burner gives a wide ribbon flame.

What is the difference between a Bunsen burner and a Meker burner?
The Meker Burner (B-0004) produces multiple open gas flames and is used when the laboratory work requires a hotter flame than a Bunsen burner can reach. It is also used for heating, sterilisation and combustion.
What does a Teclu burner do that a Bunsen burner does not?
The Teclu Burner (B-0002) is a variant of the Bunsen burner that produces a hotter flame.
Which burners in this range run on natural gas and which on liquid propane?
The Bunsen Burner - Basic - Natural Gas (B-0010) is the natural gas build and the Bunsen Burner - Basic - Liquid Propane (B-0009) the liquid propane build, and B-0009 is available in natural gas and liquid petroleum variants. The Bunsen Burner With Stop Cock (B-0006) is stated as suitable for natural gas.
What ribbon lengths are available on the fishtail burner?
The Fishtail Burner (B-0003) can be supplied in any ribbon length from 100 mm to 400 mm (4 in. to 16 in.).
Which burner has a gas control stopcock?
The Bunsen Burner With Stop Cock (B-0006) is fitted with a gas control stopcock, in addition to its adjustable air regulator.
What is a flame spreader used for?
The Flame Spreader (B-0005) sits inside the round wick of a round-wick lamp, in the airflow path, and redirects the air flow to the flame so that the fuel vapours coming off the wick are oxygenated.
Burners sit within Chemistry Lab Equipments, alongside Chemistry Lab Instruments and Science Lab Plasticware. The wider Educational Lab Equipment range covers physics, biology and maths as well.
For prices and availability on any burner in this range, for example the Bunsen Burner With Stop Cock (B-0006) or the Meker Burner (B-0004), contact Ray Export.
The Teclu burner is a laboratory gas burner actually it is a variant of the bunsen burner. It can produce a hotter flame than a Bunsen burner.
This apparatus is used to produce multiple open gas flames and it is also used for heating, sterilization, and combustion. It is used when laboratory work requires a hotter flame than attainable using a Bunsen burner.
Round wick lamps rely on hot air increasing inside their chimney to provide fresh rich air into the burner to feed the flame. Their burners are built to draw fresh air to the flame from both inside and outside of the round wick. The flame spreader sits inside the round wick in the airflow path to redirect the air flow to the flame in order to oxygenate the fuel vapors coming off the wick.
