Abstract: A self-centering vial clamp is provided. The self-centering vial clamp includes a clamp body including a vial aperture and two or more jaw slots spaced around the vial aperture, two or more clamp jaws spaced around the vial aperture, with a clamp jaw including a vial contact face and one or more jaw projections configured to engage a jaw slot of the clamp body, and two or more lever arms coupled to the two or more clamp jaws. A lever arm is configured to be manually pivoted, wherein the lever arm translates the pivoting motion into a sliding motion of the corresponding clamp jaw. Interacting lever gears formed on the lever arms constrain the two or more clamp jaws to move substantially in unison.

Abstract: A self-centering system is described for holding an object (e.g. a vial, tube or cell) to maintain the longitudinal axis of the object in the desired orientation. The system includes two cam members which are pivotably mounted on parallel axes. The cam members include sloped surfaces which are able to accommodate objects of various diameters or shapes (e.g. circular or non-circular cross-section). The cam members are biased (e.g. with weights or springs) such that the sloped surfaces are automatically brought into contact with the object to be oriented and supported.

Abstract: A magnetic stir bar is described that includes a first portion with an outer perimeter that has a shape in plan view and a center point being a geometric center of the shape. The magnetic stir bar includes a second portion with a magnet that is connected to the first portion. The second portion is arranged so that at least part of the second portion is positioned within the outer perimeter of the first portion and so that a magnetic center point of the magnet in plan view is positioned off-center with respect to the center point of the outer perimeter. A method of mixing a fluid includes providing the fluid in a mixing container with the magnetic stir bar and rotating the magnetic stir bar with a magnetic stirrer.
