A family of droplet generator chips in various designs allows for the generation of droplets in different sizes and frequencies. Integrated chips exceeding the droplet generation function e.g. with combining droplet generation with droplet storage for an afterwards separate optical analysis allowing a wide variety of experiments.

As fluidic interfaces female Mini Luer and female Luer adapters are integrated. The female Luer adapter due to their large volume not only allow to serve as fluidic interface but also as liquid reservoir.

Standard oils that are released by microfluidic ChipShop neither harming standard biological reactions nor the microfluidic chip materials can be found on the accessories site with recommendation for different chip materials.

In this multi-channel design several design options to generate droplets with different volumes are implemented. The main channel as well as the entrance channel vary in diameter enabling a large set of experiments.

Droplet generator chips of this type provide several functional droplet generator units of the same geometry on one chip. Fluidic 912 features Mini Luer interfaces and eight identical droplet generation units with a channel dimension of 80 μm at the droplet formation region.

These droplet generator designs combine size variations of one main design for the evaluation of generated droplet size under the desired conditions. For this purpose, we offer two droplet generator chips with similar design to evaluate droplet sizes. Each chip features eight individual droplet generator units and Mini Luer interfaces. Fluidic 440 is designed to generate larger droplets with channel dimensions at the droplet formation region of 80 μm, 70 μm, 60 μm and 50 μm channel width and height. In contrast, Fluidic 947 generates smaller droplets with channel dimensions at the droplet formation region of 30 μm, 20 μm, 15 μm and 10 μm channel width and height. Each size version comes with two different outlet channel widths.

Droplet generator chips with a double-cross geometry allow for the generation W/W/O emulsions, where mixing of two (or more) aquaeous solutions and subsequent encapsulation takes place in a single step on-chip. There are three designs with varying channel sizes available. All of the feature a flow-focusing junction at the second cross, allowing for the formation of droplets in a defined size and with high-throughput.
The double-cross chips serve a variety of different applications, such as such as e.g. mixing of cells with a lysis buffer and immediate encapsulation in a droplet for further downstream analysis and optical read-out.
