  • Publication number: 20210023514
    Abstract: Disclosed herein are continuous flow systems having bifurcated fluidic flow mixers. The mixers operate, at least partially, by Dean vortexing. Accordingly, the mixers are referred to as Dean Vortex Bifurcating Mixers (“DVBM”). DVBMs utilize Dean vortexing and bifurcation of the fluidic channels that form the mixers to achieve the goal of optimized microfluidic mixing.

  • Patent number: 10835878
    Abstract: Disclosed herein are fluidic mixers having bifurcated fluidic flow through toroidal mixing elements. The mixers operate, at least partially, by Dean vortexing. Accordingly, the mixers are referred to as Dean Vortex Bifurcating Mixers (“DVBM”). The DVBM utilize Dean vortexing and asymmetric bifurcation of the fluidic channels that form the mixers to achieve the goal of optimized microfluidic mixing. The disclosed DVBM mixers can be incorporated into any fluidic (e.g., microfluidic) device known to those of skill in the art where mixing two or more fluids is desired. The disclosed mixers can be combined with any fluidic elements known to those of skill in the art, including syringes, pumps, inlets, outlets, non-DVBM mixers, heaters, assays, detectors, and the like.

  • Publication number: 20200139321
    Abstract: The present invention provides a microfluidic mixing platform having a bulk, the platform including an inlet well, a microchannel, a passive capillary valve a mixing feature and an outlet. The passive capillary valve prevents unwanted capillary flow along the microchannel. The passive capillary valve comprises a widening of the microchannel relative to the direction of fluid flow, and the angle has a graduated profile. The mixing platform bulk comprises a rigid matrix capable of machine manufacture. A method of preventing backflow in a microfluidic mixer is also provided.
