Beschreibung
Zusammenfassung:	A microfluidic device (100) comprises an emulsification section (101) comprising one or more emulsification units (170); and a container section (102) comprising one or more groups of containers comprising one group of containers for each emulsification unit; each emulsification unit (170) comprising a fluid conduit network (135) comprising: a plurality of supply conduits comprising a primary supply conduit (103) and a secondary supply conduit (106); a transfer conduit (112); and a first fluid junction (120) providing fluid communication between the primary supply conduit (103), the secondary supply conduit (106), and the transfer conduit (112); each group of containers (103) comprising a plurality of containers comprising an intermediate chamber (174), a collection container (134), and one or more supply containers (131) comprising a secondary supply container, the secondary supply container (131) defining a secondary supply cavity, the secondary supply container (131) comprising a secondary orifice (177) extending from the secondary supply cavity and a primary orifice (176) extending from the secondary supply cavity, the collection container (134) being in fluid communication with the transfer conduit (112) of the corresponding emulsification unit (170) via a collection orifice of the collection container (134), the secondary supply container (131) being in fluid communication with the secondary supply conduit (106) of the corresponding emulsification unit (170) via the secondary orifice (177), the secondary supply container (131) being in fluid communication with the intermediate chamber (174) of the same group of containers (103) via the primary orifice (176), the intermediate chamber (174) being in fluid communication with the first fluid junction (120) of the corresponding emulsification unit (170) via the primary supply conduit (103) of the corresponding emulsification unit (170). Furthermore a method of manufacturing said device and a method for providing emulsion droplets using such a microfluidic device.
