A fluid mixing assembly comprising a fluid agitating element adapted to reciprocate within a fluid between a first position and a second position. The fluid agitating element having an internally disposed magnetic member adapted to couple with an external drive device.

In a method and system for forming concentrated volumes of microbeads, a polymer solution and/or suspension includes a polymer dissolved and/or dispersed in a medium. Streams of a focusing fluid and of the polymer solution and/or suspension flow towards a fluid bath, and into intersection with one another, so as to focus the polymer solution and/or suspension. The polymer solution and/or suspension stream forms microbeads in the fluid bath Some of the focusing fluid is drawn from the fluid bath, so as to concentrate the microbeads in the fluid bath. The system includes a flow focusing apparatus and a liquid-containing cell. The focusing apparatus includes polymer and focusing nozzles. The cell contains the fluid bath and has an outlet port, through which the focusing fluid is drawn.

The present invention generally relates to systems and methods for pressure driven flow crystallization. In some embodiments, the system comprises a comprising a cavity and a mixing mechanism. In some embodiments, one or more inlets facilitate the transfer of one or more reagent streams to the cavity. In some such embodiments, the mixing mechanism mixes the first and second reagent streams such that a continuous crystallization and/or generation of a product (e.g., solid particles) in the fluid.

A wireless sensor that can measure properties of a substance and transmits the properties to a remote wireless receiver is disclosed. The wireless sensor can be fully enclosed within a container containing the substance, for example, allowing remote monitoring of the properties of the substance without compromising the integrity of the closed system.

A whisk means for a frother for producing a hot chocolate beverage is adapted to rotate in the liquid to mix the heating liquid. The whisk means comprises a whisk comprising a plurality of coils, which whisk is mounted on a support, the whisk means further comprising a basket located above the whisk means, which basket is provided with one or more slots for allowing the heating liquid to melt or dissolve the hot chocolate beverage precursor.

A measuring system for automatically determining a quality of a foodstuff mixture includes a product holder for a fluid or viscous foodstuff, a housing for receiving the product holder, a sensor device for measuring a parameter value of the foodstuff, a control device, an additive dosing device for output of an additive to the foodstuff, and a mixing device which includes a mixing body arranged in the product holder and including a magnetisable or magnetic material, and a displacement device for the mixing body. The mixing device is configured to act on the additive dosing device via the mixing body to output the additive. Because the magnetically movable mixing body, arranged even before mixing, can cause the output of additive, error-susceptible human actions are avoided, without the need to open the product holder.

An impeller, for example, a Rushton impeller for a bioreactor system is disclosed. The impeller includes a hub, optionally including a slot, a plurality of blades, and one or more turbulators. The plurality of blades is disposed along a circumferential direction of the hub and spaced apart from each other. Each of the plurality of blades is coupled to at least a portion of a circumference and/or a top surface of the hub. Each blade of the plurality of blades includes a pressure face and a suction face. The one or more turbulators is disposed on at least a portion of the suction face, the pressure face, or both, of a blade of the plurality of blades.

A bottom-entry magnetic stirring device is presented, featuring an impeller assembly and an isolation sleeve connected axially in a movable manner. The impeller assembly drives material in the center of a stirring tank downward. The isolation sleeve includes a limiting structure located at the upper part of the impeller assembly, creating a downward magnetic force on the impeller assembly, restricting its maximum upward displacement. This magnetic coupling between the isolation sleeve and impeller assembly generates a downward force component, allowing the impeller assembly to remain in a suspended state while rotating. This configuration minimizes material contamination risks and eases cleaning by reducing material residues in worn or deformed areas.

A colloidal brewing system has a transparent container assembly with a watertight bottom portion and an open top portion, the container assembly adapted to contain water. A removable lid electronic housing with two replaceable electrically charged silver rod members is disposed on a bottom portion of the lid member, the rod members extending substantially to near the bottom of the container assembly. A magnetic stir assembly substantially centers an interior bottom portion of the container assembly and to rotate, in the water, on a parallel plane to the bottom portion. A receiver and transmitter coil assembly are disposed within a base container assembly, the base container assembly designed to gravitationally support the watertight bottom portion of the transparent container assembly, the receiver coil and transmitter coil assembly inductively coupled to the magnetic stir assembly. The inventive concept has a rechargeable battery, a control panel, power port members, and handle member.
