In addition, the present application further discloses a blood sample agitating device, a blood sample analysis method, and a computer storage medium.

A flask stand is configured to support a flask and includes a base ring and a plurality of legs. The base ring is configured to support a lower portion of the flask. Each leg is secured to the base ring and extends outward from the base ring. Each leg includes a body, a lattice, and an elastomeric foot. The body includes a first end portion that is secured to the base ring with the foot portion being opposite the first end portion. The lattice is formed within the foot portion and includes a plurality of members that form an open-mesh frame that defines a plurality of voids between adjacent members of the frame. The elastomeric foot is formed of an elastomer and is disposed about the lattice and within the voids of the lattice. The foot is configured to engage a surface to support the body relative to the surface.

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 method for mixing a fluid includes: dispensing a first volume of a fluid into a flexible container, the flexible container being at least partially disposed within the chamber of a support housing; repeatedly moving the support housing and the flexible container contained therein so as to mix the first volume of fluid within the flexible container; adding further fluid into the flexible container after moving the support housing to form a second volume of fluid; and manipulating a mixing element within the flexible container so as to mix the second volume of fluid.

A caulk tube adapter for allowing mixing of coloring compositions into caulk is provided. The caulk tube includes baffles on the inside surface of the tube for facilitating mixing of the caulk and coloring composition. An adapter for allowing the caulk tubes to be positioned into a paint mixer is also provided.

Provided are an enclosed stirrer using intermittent resonance and a method. The enclosed stirrer comprises: two pairs of parallel tension springs (1), a fixing bracket (2), an elastic cantilever beam (3), a cantilever beam pressure clamping device (6), an eccentric motor (4), an arc-shaped cushion block (5), and an enclosed container (8). The enclosed container (8) is mounted on the fixing bracket (2) by the tension spring (1). The elastic cantilever beam (3) is installed below the enclosed container (8) and is axially parallel to the enclosed container (8). One end of the elastic cantilever beam (3) is mounted on the fixing bracket (2) as a clamping end, the other end of the elastic cantilever beam (3) is connected to the eccentric motor (4) as a movable end. The arc-shaped cushion block (5) is connected above the eccentric motor (4). The arc-shaped cushion block (5) reciprocally strikes the bottom of the enclosed container (8) during operation of the eccentric motor (4).

A pretreatment device for food safety detection, including: a base; a vortex oscillator disposed on the base; and a container holding mechanism disposed on the base and configured to hold a container such that the container is positioned above the vortex oscillator, wherein the vortex oscillator is configured to cooperate with the container holding mechanism to treat materials contained in the container. The present disclosure further provides a pretreatment method for food safety detection. By means of the pretreatment device and the pretreatment method according to the present disclosure, it can perform pretreatment work of food safety detection efficiently and simply, and save labor costs.

A mixing apparatus, comprising a drive unit (1) with a drive (10) and a shaft (11) which is pivotable about a pivot axis (A) and which is operatively connected to the drive (10), a pivot receptacle (2) which is arranged on the shaft (11), wherein the pivot axis (A) is substantially horizontally aligned, wherein the pivot receptacle (2) comprises a base (20) on which receptacles (21, 22) are provided which extend away from the base (20) and into which holders (3) for containers (7) are insertable.

The adapter connects an aerosol or similarly shaped can to a power tool for the purpose of mixing the contents within the can. The adapter preferably connects a reciprocating power tool, such as a reciprocating saw, to a spray paint can that is necessarily shaken before use. To secure the can to the power tool, the adapter has multiple fingers that grasp the end of an aerosol can with respective tabs. The tabs catch on a ring on the topside of the spray paint can to prevent it from breaking away from the reciprocating tool during operation. To secure the adapter to the can, a collar surrounds the fingers and tightens around the fingers to securely fasten them to the can. Accordingly, the can is held in place until the collar is released and the tabbed fingers can be pulled away from the can.

A clamping platform for a mechanical shaker, which allows automated release and fastening of microtiter plates that are subject to tolerances, includes at least two mounts arranged pairwise for the releasable fastening of the microtiter plates. The platform includes clamping jaws, on which a compression spring acts, actuatable with a link control having a linear drive. In conjunction with the compression spring, the geometry of the guide links allows compensation for the dimensional tolerances of the microtiter plates that are to be fixed by clamping. The spring force of the compression spring is determined such that the clamping jaws that are loaded by the compression spring exert the required clamping force in the deployed position onto the microtiter plates to be fixed.
