Microcfluidic apparatus (1) and method for generating a dispersion. The apparatus comprises a droplet formation unit (3) comprising a feed opening (2) for supplying a to-be-dispersed phase first substance to the droplet formation unit, and an oblong droplet formation opening (14) for forming droplets of the to-be- dispersed phase first substance in a continuous phase second substance, the droplet formation opening having a first, smallest dimension W and a second, largest dimension L, wherein the second dimension L of the droplet formation opening is more than fifty times the first dimension W of the droplet formation opening. The droplet formation unit has a third dimension D in a direction from the feed opening to the droplet formation opening, wherein the third dimension D is more than two and a half times the first dimension W. The microfluidic apparatus further comprises a feed structure, in fluid communication with the feed opening for feeding the to-be-dispersed phase first substance to the droplet formation unit, wherein a flow resistance of the droplet formation unit is larger than a flow resistance of the feed structure. |
