The tesla mixer chip Fluidic 1677 is a very effective mixing tool. It features two different channel design. Each design is found twice on the chip. Booth designs enable mixing of two liquids with two Mini Luer inlets and one Mini Luer outlet. The chip is the ideal tool to evaluate mixing on a small footprint to later embed the design e.g. within a more complex microfluidic workflow. The off-the-shelf-chip can also be used for the production of lipid nanoparticles (LNPs).
