Provided herein are apparatuses and systems for mixing liquids and suspensions that include vessels with structures that improve mixing while not contacting liquid delivery components. The apparatuses and systems can include a motor drive that allows speed and directional control of rotation of the vessel. The apparatuses and systems can include one or more magnets for separating magnetic beads in a suspension. Also provided are methods using said apparatuses and systems for mixing and separation processes.

A device comprising a base and a support structure is disclosed. The base includes a vial receptacle for holding a vial. The support structure is coupled to an upper portion of the base and is configured to align a pipette comprising a pipette tip vertically over the vial receptacle. The support structure is configured to support a pipette such that an end of a pipette tip is positioned one or more predetermined depths within a vial in the vial receptacle.

A method for withdrawing a solution comprising a plurality of particles from a vial is disclosed. The method includes agitating the vial at a first predetermined mixing speed to suspend the plurality of particles in the solution. The method also includes withdrawing, during the agitating, a first volume of the solution from the vial with a pipette, such that an end of a pipette tip is positioned at a first predetermined depth within the vial.

A method for preparing an aliquot of solution comprising a plurality of particles is disclosed. The method includes agitating the solution with a baffle at a predetermined mixing speed to suspend the plurality of particles in the solution, wherein the baffle positioned at least partially within a vessel containing the solution, and wherein the vessel is engaged with a vessel receptacle configured to hold the vessel. The method also includes withdrawing, during the agitating, the aliquot of solution from the vessel with a pipette, such that an end of a pipette tip is positioned within the vessel.

Processes related to rotationally mixing a liquid composition that includes a consumer product adjunct ingredient, for example by subjecting the composition to multiple rotation cycles that include horizontally rotating the composition in a first direction and in a second direction that is counter to the first direction. Related systems and apparatuses. Processes for making consumer products from compositions thusly mixed.

A container assembly with improved mixing dynamics for mixing substances in preparation for injection by an injection device or for the dispersion of additives in the collection and analysis of biological samples is disclosed. In one configuration, the container assembly includes a first mixing element protruding into an interior of a container. With the container rotated about its longitudinal axis, the first mixing element forms at least one vortex which effectuates mixing of a first substance provided within the container interior and a second substance provided within the container interior.

A machine for making liquid or semi-liquid food products includes a frame and a thermal system, which performs at least one thermodynamic cycle using a main heat exchanger fluid, and a production unit. The production unit is provided with a processing container having a cavity which defines a processing chamber for making a liquid or semi-liquid food product, a stirrer, applied or applicable on the frame at a fixed position and fitted or fittable in the processing container, and coupling means between the processing container and the drive shaft to allow coupling and hence transmission of motion from the motor to the processing container. In particular, the stirrer is provided with an inner core and an outer covering made of different materials.

A paddle in a three-pronged fork-like shape with the middle part longer than the others cannot uniformly knead a highly viscous fluid.

A paddle includes an arm portion disposed outside a container and a paddle portion integrally formed on the distal end of the arm portion and disposed inside the container. The paddle portion includes a horizontal part, vertical parts protruding upward from both end portions of the horizontal part, and a coupling shaft portion protruding upward from the middle of the horizontal part to the arm portion. Providing an inwardly protruding portion on the upper end of the second vertical part makes it possible to mix a mixing object in an area corresponding to a non-fluid area by using the inwardly protruding portion.
