A fluid feeder includes a fluid storage unit and a pre-treatment unit. The fluid storage unit provides a fluid flow path through which a fluid mixture of a hydrophilic fluid and a hydrophobic fluid flows. The fluid storage unit is connected through a plurality of connectors to the fluid flow path having a portion, in which an ultrasound focusing unit for focusing ultrasound to disperse and mix the fluids contained in the fluid mixture by focused ultrasound is mounted, to flow the fluid mixture in the fluid flow path and to flow the fluid mixture dispersed by the ultrasound focusing unit through the fluid flow path. In the pre-treatment unit, the fluid mixture is dispersed at micrometer scale and supplied to the fluid storage unit before the fluid mixture is stored in the fluid storage unit.

Method and apparatus for controlling acoustic treatment of a sample to mediate a tagmentation process used on double stranded DNA.

A process for extracting carbohydrates from biomass and creating bioalcohol from the extracted carbohydrates. Subjecting the biomass to acid or alkali hydrolysis in a first hydrodynamic cavitation process. Filtering the first cavitated biomass to separate a first filtrate containing extracted carbohydrates. Fermenting the first filtrate to create a bioalcohol and separating the bioalcohol by distillation or similar process. Subjecting the biomass to enzymatic hydrolysis in a second hydrodynamic cavitation process. Filtering the second cavitated biomass to separate a second filtrate containing extracted carbohydrates. Fermenting the second filtrate to create a bioalcohol and separating the bioalcohol by distillation or similar process. The first and second filtrates may be combined and fermented in a single step.

Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.

In the field of automatic analyzers, as items to be analyzed are increase, various reagents differing in such properties as liquid viscosity and contact angle are being used more frequently, and this trend is expected to continue. Also, reagents now take various forms (e.g., a concentrated reagent to be diluted by the water of an automatic analyzer), and so does dilution water. Such being the case, the invention provides an automatic analyzer capable of sufficient stirring regardless of items to be analyzed. To sufficiently stir a substance to which a reagent has been added, the automatic analyzer is designed to alter stirring conditions after a given amount of time has passed since the addition of that reagent.

A nanobubble-producing apparatus includes a liquid vat provided with a bubble-containing-liquid inlet in an upper part thereof and a bubble-containing-liquid outlet in a bottom part thereof, a microbubble-containing-liquid supply unit to supply microbubble-containing liquid that contains microbubbles to the bubble-containing-liquid inlet of the liquid vat, an ultrasonic collapse unit to radiate ultrasonic waves to the inside of the liquid vat so that an ultrasonic collapse field in which the collapsing of the microbubbles with the ultrasonic waves is concentrated and nanobubbles are generated is formed at a location where the microbubble-containing liquid supplied into the liquid vat through the bubble-containing-liquid inlet flows downward, and a nanobubble-containing-liquid extraction portion where the nanobubble-containing liquid that contains the nanobubbles generated by the ultrasonic collapse unit is taken out of the liquid vat through the bubble-containing-liquid outlet.

An apparatus for disintegration (or mixing) of a solid in a vessel containing liquid, has a control unit and an ultrasound transducer for generating ultrasonic energy under control of the control unit. A coupling medium in communication with the ultrasound transducer is adapted to receive the vessel. Ultrasonic energy is transferred to the contents of the vessel such that in use the ultrasonic energy causes disintegration of the solid into the liquid contained in the vessel. An agitating mechanism is adapted to agitate the disintegrated solid in the liquid contained in the vessel. The agitating mechanism may include a paddle having a coating of flavouring material. A method for disintegration of a solid in a vessel is also disclosed.

Disclosed is an ultrasonically-enhanced continuous and large-scale production method for nano-formulations. Specifically disclosed is a preparation system for continuous production of nano-formulations, comprising (a) a first pipe, (b) a second pipe, (f) an ultrasonic device, (c) a combined pipe and (e) a (fluid) outlet thereof. The first pipe and the second pipe are connected to the combined pipe. A first phase solution enters the combined pipe through a first pipe outlet, and a second phase solution enters the combined pipe through a second pipe outlet. The ultrasonic device acts on the part or the whole of the combined pipe. The first phase solution and the second phase solution are turbulently mixed in the combined pipe to form a combined phase, and flow out through the outlet of the combined pipe.
