A dispensing device, comprising a plurality of microfluidic pumps, microfluidic valves, and a microfluidic mixer chip, for receiving and mixing microfluidic amounts of a plurality of fluids having differing viscosities, is disclosed. The device includes a plurality of pathways for moving fluids from associated reservoirs to the microfluidic mixer chip. A mix controller controls the microfluidic pumps and valves so that the fluids, having different viscosities, can be accurately mixed at specified microfluidic amounts or volumes according to a specified microfluidic recipe, and the microfluidic mixture dispensed from the device. The device can be in communication with a software application implemented on a mobile compute device, such as a smartphone, and receive instructions for implementing the specified microfluidic recipe from the software application such that the operation of device components is at the direction of the software application executed on the mobile compute device.

Provided is an ultrafine bubble generating method and an ultrafine bubble generating apparatus capable of efficiently generating a UFB-containing liquid with high purity. To this end, a flow passage inner volume is varied by using a flow passage inner volume varying element, the liquid is pressurized such that the liquid passes through a narrow portion at high speed and flows into a depressurizing area.

The present invention relates to systems and methods for manipulating droplets within a high through put microfluidic system.
