Burners, Meker

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 tempera- ture of flame can reach 1775 °C.
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.

Flame Temperature Distribution
The Bunsen/Tirrill burner and Meker burner differ not only in the higher maximum temperature produced, but also in heat distribu- tion within the flame.

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. 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) See free video at flinnsci.com.
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 tempera- ture of flame can reach 1560 °C.
*AP1019, natural gas model and AP1020, bottled gas model are furnished with flame retainers. AP1018, artificial gas model, is not furnished with a flame retainer.
