Provided is a stirring device that allows a weight measurement during a rotation operation to be accurately performed while suppressing increase in reinforcement structures required for support of a stirring container and suppressing increase in weight. A device frame is provided with legs, a heating kettle is provided with a reinforcement base attached on the bottom side, a motor bed is provided to support a cutter/motor unit to the reinforcement base or the device frame, load cells are provided to indirectly measure a change in weight of a stirring substance in the heating kettle during a rotation operation of the cutter/motor unit, and closed reinforced structures are configured to include the heating kettle, the cutter/motor unit, the reinforcement base, and the supporting stand as reinforcing members.

A method for enhancing mixing and aeration of a liquid reaction medium in a toroidal bioreactor vessel includes dispensing a liquid reaction medium into an interior of a toroidal bioreactor vessel, the interior being bounded by an inner surface, a textured surface being arranged on at least a portion of the inner surface, the textured surface having a plurality of upstanding protuberances. The toroidal bioreactor vessel is rotated in an orbital motion such that there is a resonant frequency traveling wave of the fluid orbiting in one direction in the interior of the toroidal bioreactor vessel when a particular orbital speed is imparted to the toroidal bioreactor vessel.

A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

Mixing devices and associated methods are described herein. A mixing device configured in accordance with embodiments of the present technology can include, for example, a plate configured to rotate about a longitudinal axis and a plurality of enclosures coupled to the plate. The enclosures can each include (a) at least one sidewall that defines an oblique angle with the plate and (b) a chamber configured to receive a media and a fluid. The enclosures can be fluidly coupled to a fluid source for receiving the fluid in the chambers. When the plate is rotated, the enclosures revolve about the longitudinal axis to mix the media with the fluid in the chambers.

Apparatuses and methods are provided for use in the extraction of botanical resins from plant-based source materials. The apparatuses comprise a container operable to hold liquids. The container may be closed using a first lid. The first lid may comprise a center hole through which a whisk may be inserted and locked in place. The whisk is operable to rotate using a rotation mechanism and subsequently stirs the contents of the container. The rotation may be manual or motor driven. After stirring, the first lid is removed and a second lid is attached. The second lid may comprise an integrated mesh filter and a spout so that liquid contents of the container may be easily poured out.

Described here are apparatuses and methods for producing a composition comprising nano-bubbles dispersed in a liquid carrier. One such method includes flowing a liquid carrier from an inlet through at least two channels each including a triboelectric material, including flowing the liquid carrier such that a Reynolds number of the flow of the liquid carrier through the at least two channels is less than 3000. Flowing the liquid carrier through the at least two channels produces vibrational energy that causes: (i) the liquid carrier to contact the triboelectric material such that an electric charge is generated in the triboelectric material; and (ii) the liquid carrier to separate from the triboelectric material such that the electric charge is discharged to the liquid carrier to form nano-bubbles dispersed in the liquid carrier.
