Devices, systems, and methods for charging fluids are disclosed. The charging of fluids improves the mixing of fluids in microfluidic systems. The charging is performed by producing an ion field between an ionizing electrode and an opposed ground electrode. A fluid-containing vessel is positioned between the opposed electrodes and the ion field charges the fluid in the vessel.

A microfluidic chip, device, system, the use thereof and method for the generation of aqueous droplets in emulsion oil for nucleic acid amplification.

A portable cooler includes a cooler body formed of an insulating shell defining an interior storage section, an insulated cooler lid coupled to the cooler body, and a storage structure formed within the insulated cooler lid for storing one or more plates. The plates can be stored in a recessed portion of the insulated lid, which may include a groove or removable lip to retain the plates. A utensil storage structure is provided to store one or more utensils. Sharp utensils may include safety mechanisms to inhibit unwanted removal.

A mixing assembly includes a bag of appropriate size, configuration, shape and material and a closable spout that may have extensions of various lengths, shapes and configurations to provide enhanced mixing of a component contained in the bag upon the addition of a second component. Once the closure of the spout is removed, the second component, typically a liquid such as water, milk, juice, chemical, oil substrate, or the like, can be added to the container for mixing. After the closure is refitted, the two components are mixed then consumed or dispensed, either by removing the closure or from a separate spout or nozzle fitted to the closure.

A method and an apparatus for producing various types of microdroplets are provided. The apparatus has a cross intersection portion 7 at which a first continuous phase 2, a first dispersion phase 4, and a second dispersion phase 6 intersect with each other; a first liquid feed device 12 controlling the first dispersion phase 4; a second liquid feed device 13 controlling the second dispersion phase 6; and a control device 11 connected to the first liquid feed device 12 and the second liquid feed device 13, in which the first liquid feed device 12 and the second liquid feed device 13 are controlled by a signal from the control device 11 so that microdroplets 9 formed of the first dispersion phase 4 and microdroplets 10 formed of the second dispersion phase 6 are sequentially produced.

An apparatus for mass producing monodisperse microbubbles contains a microfluidic flow focusing device. The microfluidic flow focusing device includes a dispersed phase fluid supply channel having an outlet that discharges into a flow focusing junction, a continuous phase fluid supply channel having an outlet that discharges into the flow focusing junction, and a bubble formation channel having an inlet disposed at the flow focusing junction. The configuration of the flow focusing junction is such that, in operation, a flow of dispersed phase fluid discharging from the outlet of the dispersed phase fluid supply channel is engageable in co-flow by a focusing flow of continuous phase fluid discharging from the outlet of the at least one continuous phase fluid supply channel under formation of a gradually thinning jet of dispersed phase fluid that extends into the inlet of the bubble formation channel.

The present invention relates to a mixer and applicator device for mixing and applying a compound obtained by means of mixing two products which comprises: a casing which internally houses a movable push rod, where the casing allows housing a container which is fixed to the casing, a drill or rotor for driving the movable push rod, a base part coupled to a rear portion of the drill or rotor, at least one guide which is secured at a first end on the base part and at a second end on the casing where the ends of the at least one guide are fixed on the casing such that the at least one guide allows the fixing and rotation of the casing, and at least one member going through the at least one guide respectively such that the rotation of the casing does not take place in response to the actuation of the drill or rotor. As a result of this device it is possible, using the same device, to prepare a compound by means of mixing a base product and a catalyst and to further be able to dispense it without having to perform any disassembly or adaptation whatsoever in the container or in the means used for the mixing.

A fluid mixing structure (10) for mixing at least two fluidic components has a flow inlet port and a flow outlet port and comprises a contraction zone (12), an expansion zone (14), and a retention zone (16), arranged in this order in an inflow direction (IFD) of a fluid flow to flow through said fluid mixing structure (10) and being composed of said at least two fluidic components, and a flow splitter (32) arranged In a space (30) formed by said expansion zone (14) and said retention zone (16) to split said fluid flow in a first sub fluid flow and a second sub fluid flow flowing in a first flow path and a second flow path, respectively, formed in the fluid mixing structure, and to mix said first and second sub fluid flows within said space (30) to generate and discharge a homogenized fluid flow, wherein said flow splitter (32) is arranged and configured to let any flow element of each of said first and second sub fluid flows prior to their mixing have a non-zero average flow component in said inflow direction (IFD).

A tintometric machine includes an external frame made from rigid material, which defines an internal area. The internal area houses at least one dispenser system, which can dispense at least one fluid, such as paint or dye, into a vessel or container. The dispenser system of the tintometric machine, includes one or more dispenser mechanisms and a plurality of canisters or containers. Each of the dispenser mechanisms includes at least one pump and at least one valve assembly, and the canisters or containers are connected to one or more dispenser mechanisms. The external frame of the machine has a shell-shaped structure that can be opened to divide the machine into at least two portions. Each portion contains a part of the dispenser system. By dividing the machine into portions, an inspection area is defined between the portions, which is accessible to an operator.

Assembly of a tintometric machine and a trolley includes an external frame and a dispenser system. The dispenser system dispenses a fluid into a vessel or container, when the vessel or container is positioned in a dispensing station. The trolley includes: a supporting top, whereon the container can be positioned; rotary elements allowing the trolley to move; a gripping element, through which the user can grip the trolley and move it. The dispensing station has a housing into which the trolley can be positioned. The assembly includes a plug-socket system, wherein a first part of the system is located on the trolley and a second part is located in the dispensing station. The parts of the system can be assembled together when the trolley is placed into the housing of the dispensing station, for the purpose of conducting an electric current. The trolley includes an actuating device that can move the supporting top.
