Meker models product hotter flames than standard bunsen burners. For use with natural (methane) gas, these Meker burners are made of nickel-plated brass and a heavy diecast base with a chemically resistant acrylic finish.
Meker burners are fitted with a perforated steel head which gives multiple small, but very hot flames.
These burners do not require an air regulator.
The 43mm model has a safety handle, is fitted with a No. 5 jet and is supplied with alternative jets, sizes 1, 2 and 3.
