A MekerâFisher burner, or Meker burner, is an ambient air laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion. It is used when laboratory work requires a hotter flame than attainable using a Bunsen burner, or used when a larger-diameter flame is desired, such as with an inoculation loop or in some glassblowing operations. The burner was introduced by French chemist Georges MĂ©ker in an article published in 1905. [1]
The MekerâFisher burner heat output can be in excess of 12,000 BTU (13,000 kJ) per hour (about 3.5 k W) using LP gas. [2] Flame temperatures of up to 1,100â1,200 °C (2,000â2,200 °F) are achievable. Compared with a Bunsen burner, the lower part of its tube has more openings with larger total cross-section, admitting more air and facilitating better mixing of air and gas. The tube is wider, and its top is covered with a plate mesh, which separates the flame into an array of smaller flames with a common external envelope, ensures uniform heating, and also preventing flashback to the bottom of the tube, which is a risk at high air-to-fuel ratios and limits the maximal rate of air intake in a Bunsen burner. The flame burns without noise, unlike the Bunsen or Teclu burners. [1] [3]
