Abstract (en)
A fluidic dispensing device (110) includes a housing (112), an ejection chip (118) and a stir bar (132). The housing has an exterior wall (140-1) and a chamber. The exterior wall has a chip mounting surface (140-2) defining a first plane and has an opening (140-3). The chamber defines an interior space and has a port coupled in fluid communication with the opening (140-3). The ejection chip is mounted to the chip mounting surface of the exterior wall. A planar extent of the ejection chip is oriented along the first plane, the ejection chip is in fluid communication with the opening, and a fluid ejection direction of the ejection chip is substantially orthogonal to the first plane. The stir bar is located in the chamber. The stir bar has a rotational axis (160), and the rotational axis of the stir bar is substantially perpendicular to the fluid ejection direction, or parallel to the planar extent of the ejection chip.
