This disclosure provides for devices, methods, and systems for generating a plurality of droplets within a collecting container at an extremely high rate (e.g., of at least 1 million droplets per minute, etc.), each of the plurality of droplets comprising an aqueous mixture for a digital analysis, wherein upon generation, the plurality of droplets is stabilized in position within a region of the collecting container. The inventions enable partitioning of samples for digital analyses at unprecedented rates, where readout of signals from targets within such partitions can still be achieved in accordance with various assays.

A beverage dispensing nozzle includes a housing having an upper end opposite a lower end, and an inlet at the upper end that is configured to be placed in communication with a source of a base liquid. The beverage dispensing nozzle further includes a chamber within the housing and in communication with the inlet. An aerator is in communication with the chamber, and the aerator includes a plate having apertures. A flavor inlet valve is in communication with a source of a flavoring and is arranged downstream of the aerator. The flavor inlet valve is configured to dispense the flavoring into the housing. The beverage dispensing nozzle additionally includes a nozzle tip arranged at the lower end of the housing.

A wine aerator includes a gas conduit having a proximal end in fluid communication with a distal end, wherein the gas conduit passes through a seal and wherein the distal end is configured to be insertable into an inside of an uncorked wine bottle. A gas source is connectable to the proximal end of the gas conduit and is in fluidic communication with the gas conduit, wherein the gas source comprises an air pump having an adjustable flow rate of at least 0.1 liters per minute up to a maximum of 20 liters per minute. A bubble-generating aeration element is disposed at the distal end of the gas conduit and in fluidic communication with the gas conduit. The bubble-generating aeration element comprises a porous material having an average pore size of at least 1 micron up to a maximum of 500 microns.

A foam dispenser includes a dispensing outlet, a pre-mixing chamber receiving liquid from a liquid source and air from an air source, a mixing chamber downstream of the pre-mixing chamber and proximate the dispenser outlet, and a first conduit coupling the pre-mixing chamber to the mixing chamber.

There is provided a dissolver tube to generate a pressure change to a fluid to change a physical property of the fluid, the tube comprising: a hollow tubular outer body; an inlet cap coupled to the body at an inlet thereof; an outlet cap coupled to the body at an outlet thereof; and a plurality of mesh screens arranged between the inlet cap and outlet cap, wherein each mesh screen has a plurality of micro-holes formed therethrough, each micro-hole having a Venturi structure, thereby to momentarily continuously contract, relax, and shear the fluid passing through the tube.
