    Abstract: A reagent deposition area of a reagent dispensing system may include a dispersion bar located above a conveyor system, and a reagent module coupled to the dispersion bar. The reagent module may include at least one reagent dispensing device to dispense a number of reagents on a substrate carried on the conveyor system, and a module frame electrically and mechanically coupling the reagent dispensing device to the reagent dispensing system. The dispersion bar moves the reagent module in two coordinate directions planar with the surface of the substrate.

    Abstract: An example device includes a first microfluidic channel in communication with a fluid reservoir to receive cell-containing fluid from the fluid reservoir. The device further includes a second microfluidic channel in communication with the fluid reservoir to receive cell-containing fluid from the fluid reservoir. The device further includes a first sensor disposed at the first microfluidic channel, a second sensor disposed at the second microfluidic channel, a first dispense nozzle disposed at an end of the first microfluidic channel, and a second dispense nozzle disposed at an end of the second microfluidic channel. The first microfluidic channel is shaped to convey cells of a first size range, and the second microfluidic channel is shaped to convey cells of a second size range that is different from the first size range.

    Abstract: In one example in accordance with the present disclosure, a fluidic ejection controller is described. The fluidic ejection controller includes a firing board to pass electrical control signals for ejecting fluid from a fluidic ejection device. An ejection board of the fluidic ejection controller is electrically coupled to, and selectively removable from, the firing board to pass the electrical control signals to the fluidic ejection device. Electrical pins are disposed on the ejection board in a pattern that matches a pattern of electrical pads on the fluidic ejection device. The electrical pins interface with corresponding electrical pads to pass the electrical control signals from the ejection board to the fluidic ejection device.
