The double emulsion droplet chip Fluidic 1480 provides two droplet generator units with a double-cross geometry, featuring varying channel/nozzle sizes at the second cross. It comes with a specific surface coating that facilitates the generation of double emulsions. This includes the incorporation of droplets or cells from the first channel intersection into a further droplet shell at the second channel intersection.

Each unit consists of two crossings, each with a flow-focusing geometry, connected by a meander channel. The surface comes partially treated to produce W/O/W (water-in-oil-in-water) droplets. However, this chip can also be purchased without pretreatment to mix two aqueous phases through the meander structures and generate W/W/O droplets.

Fluidic 1480 features standard Mini Luer interfaces to seamlessly connect to a pump system of choice. For double emulsion experiments, at least three individual pump channels are required.
