摘要： The present invention relates to a microfluidic device and method for providing emulsion droplets. The device comprising: a microfluidic section comprising one or more microfluidic units; and a well section comprising one or more groups of wells comprising one group of wells for each microfluidic unit; the well section and the microfluidic section forming a fixedly connected unit such that each group of wells forms a fixedly connected unit with a respective corresponding microfluidic unit, each microfluidic unit comprising a fluid conduit network comprising: a plurality of supply conduits comprising a secondary supply conduit and a primary supply conduit comprising a capillary structure having a volume of at least 2 μL; a transfer conduit; and a first fluid junction providing fluid communication between the primary supply conduit, the secondary supply conduit, and the transfer conduit; each group of wells comprising a plurality of wells comprising a collection well and one or more supply wells comprising a primary supply well, the collection well being in fluid communication with the transfer conduit of the corresponding microfluidic unit, the primary supply well being in fluid communication with the primary supply conduit and the secondary supply conduit of the corresponding microfluidic unit.

摘要： The present invention relates to a microfluidic device, a method for manufacturing a microfluidic device, and a method for provision of double emulsion droplets using a microfluidic device. Furthermore, the present invention relates to an assembly configured to supply pressure to the microfluidic device for provision of double emulsion droplets. Furthermore, the present invention relates to a kit comprising a plurality of microfluidic devices and a plurality of fluids configured for use with the microfluidic device for provision of double emulsion droplets. The microfluidic device comprises a transfer conduit comprising a first transfer conduit part having a first affinity for water; and a collection conduit comprising a first collection conduit part having a second affinity for water being different from the first affinity for water. A well section and a microfluidic section of the microfluidic device are fixedly connected to each other.
