Abstract

A static micro-mixer has a mixing chamber (12), inlets (5) for at least two fluid fractions, each with at least one opening (6) into the mixing chamber, and at least one outlet from the mixing chamber. The openings of the fluid inlets are arranged alternately in at least two planes, with the openings in one plane being offset from those in the adjacent planes.
