A paint container holder for use in a paint mixer, the paint container holder capable of receiving a paint container with a square, tapered square or cylindrical shape.

An apparatus for preparing a reagent solution includes an enclosure and a container disposed within the enclosure. The container defines an internal cavity having a compressible volume and defines a passage providing fluidic communication between the internal cavity and the exterior of the container. Optionally, a compressible member is disposed within the internal cavity. A reagent is disposed within the internal cavity.

An apparatus having a plate mountable on an oscillating multi-function tool and having a plurality of sample apertures sized to receive sample vials. The sample apertures may be lined with resilient grommets or have a chamfered edge. The apparatus may further have a weighted base and housing with vibrating isolation means for holding the tool during operation. The apparatus may further have a timer to allow for timed operation. The method including providing a plate mounted on the arbor of an oscillating multi-function tool, inserting a sample vial in a sample aperture and turning on the tool. The method may further include operating the tool for a fixed time and providing a housing and base to hold the tool during operation.

Method and apparatus to agitate a liquid are disclosed herein. An example apparatus includes a carrier having a base that includes a ridge extending from the base and a collar extending from the base. The example apparatus also includes a container supported on the base, the container movable between (A) a locked positon in which the ridge fixedly engages the container to non-rotatably couple the container to the base and (B) an unlocked position in which the container is disengaged from the ridge and the container is rotatable about the collar.

[Problem] To provide a agitation/defoaming method and device with which both of uniformity in dispersion of object to be processed and reduction of air bubbles can be achieved with high precision. [Solution] Provided is a agitation/defoaming method for producing orbital and spin motions of a container containing object to be processed by a device provided with orbital and spin drive motors that can independently control the velocities of the orbital and spin motions. Both defoaming and agitating treatments with high precision can be achieved by respectively performing a reverse rotation superimposition processing, wherein the rotational frequency of the spin drive motor is obtained by superimposing the first rotational frequency in a direction opposite to the direction of the orbital motion on the frequency of the orbital motion, and a same rotation superimposition processing, wherein the rotational frequency of the spin drive motor is obtained by superimposing the second rotational frequency in the same direction as the direction of the orbital motion on the frequency of the orbital motion, at least once.

Disclosed herein are devices, apparatuses, and methods for grinding of samples. A method includes securing a sample vial in a holder attached to a connecting linkage, the sample vial having a grinding media in the sample vial. The method includes rotating a crank that is operatively coupled to a proximal end of the connecting linkage at a proximal pivot point so that the proximal pivot point undergoes rotational motion. The method includes restricting a distal pivot point of the connecting linkage to a linear path, the distal pivot point near a distal end of the connecting linkage. A result being that the sample vial undergoes a combination of rotational and linear motion.

The invention discloses a platelet oscillating storage box, which includes a box body. The box body is provided with six circular array and connected rotating cavities. There are five storage blocks in the rotating cavity, and the storage blocks are provided with storage. A cavity, a storage block is fixed on the lower end wall of the storage cavity, and an end of the storage cavity close to the center of the array is provided with a fixed block that is symmetrical up and down, and a movable clamping block is provided between the fixed blocks. The clamping device can be used to clamp the test tube containing the platelets in the storage cavity, and the storage cavity is independent and communicates with the thermostat independently. When taking or storing platelets, the thermostatic conditions in the storage cavity to be placed are blocked. Cut off, reducing energy loss, without destroying the constant temperature environment in other storage chambers, and prolonging the storage time of platelets. Secondly, the sealing device can keep the storage chamber sealed, and the sealing cover and the storage chamber remain locked during the oscillation process. Ensure constant temperature in the storage chamber.

Provided herein are methods and devices for identifying and/or distinguishing UCA formulations and specifically activating such formulations to produce UCA suitable for in vivo use.
