An apparatus for preparing gas mixtures from constituents taken in a given proportion which incorporates sources of gas mixture constituents connected to pressure-reducing valves and to a device for stabilizing absolute pressures of the gas mixture constituents an outlet of which communicates with a device for setting a proportion between the gas mixture constituents consisting of a distributor which is series-connected to at least two－depending on the number of the gas mixture constituents－sets of capillary tubes featuring all the same friction head. The device for setting the proportion between the gas mixture constituents is connected to a main mixer of the gas mixture components an outlet of which communicates with a controller of absolute pressure of the gas mixture.
