Manometric flame apparatus


Accession Number:


This apparatus consists of a rectangular piece of wood with various metal attachments connect to and through it. The wood is varnished and thick enough to allow pipes or connections to run through it.

On the front of the largest face there is attached a smaller wooden rectangular section that protrudes from the front. Above this there are two metal faucet-like pieces consisting of short lengths of open pipes facing directly upwards from the face and two rotating arms, one beside each pipe, apparently to open and close the pipes. Above this, there are circular metal plates out of which protrude metal pipes, three from each plate. Two of these pipes point upwards, the other downwards.

On the opposite face from the attachments described above there is a rectangular plate fixed at about the level of the circular plates described above. Two open pipes, larger than those on the other side, protrude directly upwards from this.

At the bottom of the wooden block, protruding perpendicularly from the face, there is a brass-coloured pipe. This is open and has ridges at the end.

Dimensions (cm): Length = 16, Height = 6, width = 13


This is part of an manometric flame apparatus, used to control the flow and direction of gas used to run manometric flame instruments, such as those constructed by Rudolph Koenig, for example, the Koenig Analyzer (


Very Good: The wooden block is in good condition. The metal pieces are somewhat oxidized but with few scratches or marks. The piece appears little-used.
