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 apparatus includes a pipette dispenser to control dispensing of a volume to a dispensing location. A tip is operatively coupled to the pipette dispenser. The tip includes an electromechanical print head to dispense the volume from the pipette dispenser to the dispensing location based on a command from the pipette dispenser that indicates an amount of the volume to be dispensed from the print head.

Abstract: A reagent module may include a first reagent dispensing device to dispense a first range of volumes of a first reagent, and a second reagent dispensing device to dispense a second range of volumes of a second reagent where the second range of volumes is more voluminous relative to the first range of volumes. The reagent dispensing system may further include a third reagent dispensing device to dispense a third range of volumes of a third reagent where the third range of volumes is more voluminous relative to the second range of volumes.

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.
