Abstract: Methods and apparatuses for mixing a fluid/media for an assay are disclosed herein. In an embodiment, a mixing device for an immunochemistry system includes a pipette configured to aspirate fluid and/or paramagnetic particles from or dispense fluid and/or paramagnetic particles into a cuvette, at least one nonconcentric mass configured cause the pipette to move in a mixing motion, and a control unit configured to activate the at least one nonconcentric mass while the pipette is located within the cuvette so as to mix the fluid and/or paramagnetic particles within the cuvette.

Abstract: An apparatus for treating a tooth includes a proximal chamber and a distal chamber disposed distal the proximal chamber and in fluid communication with the proximal chamber by way of a transition opening. The distal chamber includes an access opening disposed apart from and distal to the transition opening, the access opening to provide fluid communication between a treatment region of the tooth and the distal chamber. The apparatus includes a liquid supply port disposed to direct a liquid stream into the proximal chamber and over at least a portion of the transition opening. The apparatus includes an impingement member arranged within a path of the liquid stream, the impingement member having one or more surfaces positioned to redirect at least a portion of the liquid stream across at least a portion of the transition opening.
