The fluid channel has a channel inlet, a channel outlet, and a passage between the channel inlet and the channel outlet. The channel inlet is in fluid communication with an inlet port of a chamber. The channel outlet is in fluid communication with an outlet port of the chamber. The passage is in fluid communication with an opening in an exterior wall. The fluid channel has a first corner structure in the passage. A stir bar is located in the chamber to generate a fluid flow through the fluid channel when rotated. A first flow director member is positioned adjacent the channel inlet.
