According to embodiments of the present disclosure, apparatuses, systems, and methods are provided that enable the maintenance of homogeneity of biomaterials during aseptic fill-finish. In various embodiments, an apparatus for aseptic fill-finish provided herein includes an agitation device. The apparatus further includes a platform coupled to the agitation device. The platform is rotatable about a first axis. The apparatus further includes at least one shaft extending from the platform. The shaft is adjustable in length. The apparatus further includes at least one arm extending from the shaft. The at least one arm has at least one fixation mechanism. The at least one fixation mechanism is configured to receive a container having a sealed compartment containing a biomaterial and maintain the container in a substantially vertical orientation. The platform is configured to engage at least a portion of the container.

A sample tube includes a cylindrical wall and a first end and a second end. The first end of the sample tube is closed by a base, such that a sample-receiving space with a longitudinal axis is formed between base and cylindrical wall. The second end has a closure piece connected releasably thereto. A weight element is received inside the receiving space and is shaped and dimensioned in such a way that the weight element can rotate freely in the receiving space only about the longitudinal axis of the latter. The application further relates to a method and a device with which a sample located in the sample tube can be dispersed or homogenized by rotational movement of the sample tube.

Accordingly, in some embodiments of the disclosure, a multi-chambered assay device is provided, which is configured for arrangement on a disc, as well as configured to process an individual sample. A plurality of such assay devices can be arranged along a periphery of the disc at a distance/radius from the center, such that a plurality of individual samples can be processed, e.g., one per assay device. In addition, in an arrangement that a plurality of assay devices are used, they can be spaced apart such that they balance the disc during rotation (which can be with samples contained in one or more of the assay devices, a plurality, a majority, or all of the assay devices).

Devices and methods for handling liquids are provided. The devices and methods make use of specifically controlled centrifugal forces to drive liquid flow between two cavities connected by a conduit such that as liquid flows into the second cavity, a gas volume is trapped in the second cavity and a pressure of the gas increases, allowing for pneumatic control of liquid flow. The devices and methods facilitate one or more of the mixing, metering and sequencing of liquids, for example on a microfluidic device.

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.

Disclosed in the present invention is a blood sample analyzer, including a sample conveying device, a first agitating device, a second agitating device and a controller, etc. When the first agitating device drives a sample container placed in a sample container accommodating hole to agitate a blood sample, a bottom of the sample container is kept lower than an opening of the sample container. In addition, the present invention further discloses a blood sample agitating device, a blood sample analysis method, a blood sample agitating method, and a computer storage medium.

Methods and apparatus to mitigate bubble formation in a liquid are disclosed. An example apparatus disclosed herein includes a bottom wall, a first baffle cantilevered from the bottom wall, and a second baffle cantilevered from the bottom wall. The first baffle is spaced apart from the second baffle, and the first baffle and the second baffle are positioned radially relative to an axis of rotation of the apparatus.

A selective catalytic reduction (SCR) system is disclosed. The SCR system may include a mixing tube with a mixing tube inlet; a diesel exhaust fluid (DEF) injector proximate to the mixing tube inlet; and a flow control device proximate to the mixing tube inlet, wherein the flow control device is positioned within the mixing tube or affixed to the mixing tube inlet, and wherein the flow control device includes a plurality of vanes arranged around a center of the flow control device.

An apparatus for and method of enabling enhanced, selective agitation of liquid containing a solid-phase reagent. The apparatus includes at least one liquid-bearing container, a circular tray, and a motor. The liquid-bearing container(s) includes at least one internal baffle that imparts turbulent agitation to the liquid when flowing from one end of the container to an opposite end. The circular tray is adapted for selective rotation about a vertical axis of rotation. The rotary circular tray assembly includes container-receiving stations that selectively retain a respective liquid-bearing container in an inclined or pitched orientation with respect to a horizontal plane. The motor creates centrifugal force, which causes liquid in the container(s) to travel from the first end of the container to the second end of the container via the internal baffle(s), agitating the liquid and the solid-phase portions of the reagent. When gravitational force exceeds the centrifugal force, liquid in the container(s) travels from the second end of the container to the first end of the container via the internal baffle(s), again agitating the liquid and the solid-phase portions of the reagent.

Methods and apparatus to mitigate bubble formation in a liquid are disclosed. An example apparatus disclosed herein includes a bottom wall, a first baffle cantilevered from the bottom wall, and a second baffle cantilevered from the bottom wall. The first baffle is spaced apart from the second baffle, and the first baffle and the second baffle are positioned radially relative to an axis of rotation of the apparatus.
