Select Your Laboratory
Gas Burner
Your burner will operate most efficiently if you take the time to learn about the nature of
your gas source. This knowledge will enable you to make your burner selection on the
basis of the type of gas available in your school laboratory. Select your burner to agree
with your gas source.
The three most common gas sources are as follows:
• Artificial gas (e.g., coal gas, water gas)—Generally low BTU content (800 BTU or less)
• Natural gas (e.g., methane)—Medium BTU content (1000 to 1100 BTU)
• Bottled gas (e.g., propane, mixtures of propane and butane)—High BTU content (2000
to 3000 BTU)

Testing Laboratory Burners
for Improved Safety
Laboratory burner designs have been around for 100 years—but there is still
room for improvement. We have recently worked with our manufacturers to
modify the design of adjustable-gas Tirill and Meker burners for greater safety
and ease of operation. All of our laboratory burners undergo rigorous testing
procedures for both safety and performance. Testing criteria ensure that our
laboratory burners are leak-proof, function properly and are resistant to corrosion.
Trust Flinn Scientific to keep safety first!
Burners, Meker
Meker, or high temperature burners are required where an extremely hot flame is
needed. A Meker cap on the burner forms many short, small, uniform blue heat cones
and eliminates back-flashing. Accepts burner tubing 3/8" inside diameter (Catalog No.
AP8286). Maximum temperature of flame can reach 1775 °C.
Catalog No. Description Type of Gas Price/Each
AP1021 Meker Burner Artificial $77.90
AP1023 Bottled (Liquid Propane) 79.23
AP1022 Natural 82.95
Burners, Portable, Laboratory
A self-contained laboratory burner. Ideal as a safer alternative to alcohol burners. Burner
assembly mounts on a butane canister. With the gas control valve wide open the “burn
time” for a fresh canister should be approximately three hours. Fully adjustable gas
control valve. Air supply is fully adjustable using knurled screw knob. A 3" diameter drip
catcher is permanently mounted in the burner assembly. The drip catcher also acts as a
heat dissipator to prevent burner heat from being transferred to the area of the burner
assembly where the gas control is adjusted. Includes one butane cartridge.

Burners, Tirrill
Unlike a Bunsen burner, a Tirrill burner allows adjustment of both the air supply and
the gas supply. Adjustable air ports regulate the air supply and a brass needle valve
regulates the gas supply. Accepts burner tubing 3/8" inside diameter (Catalog No.
AP8286). Maximum temperature of flame can reach 1560 °C.

The Bunsen/Tirrill burner and Meker burner differ not only in the higher
maximum temperature produced but also in heat distribution within the flame.
