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: According to an example, a microfluidic apparatus may include a fluid slot, a foyer in fluid communication with the fluid slot via a channel having a relatively smaller width than the foyer, a sensor to detect a presence of a particle of interest in a fluid passing through the channel, a nozzle in fluid communication with the foyer, and an actuator positioned in line with the nozzle. The microfluidic apparatus may also include a controller to receive information from the sensor, determine, from the received information, whether a particle of interest has passed through the channel, and control the actuator to expel fluid in the foyer through the nozzle based upon the determination.

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: In one example in accordance with the present disclosure, a fluid ejection controller is described. The fluid ejection controller includes a firing board to pass control signals to a fluid ejection device to eject fluid from the fluid ejection device. A mount pivotally holds the firing board between a disengaged position where electrical pins of the firing board are not in contact with electrical pads of the fluid ejection device and an engaged position where the electrical pins are in contact with the electrical pads. The mount includes a slot to receive the fluid ejection device and at least one biasing spring to bias the firing board away from the fluid ejection device during insertion of the fluid ejection device. The fluid ejection controller also includes a handle coupled to a cam shaft to move the firing board between the disengaged position and the engaged position.

Abstract: A fluid ejection system, in an example, includes at least one nozzle of at least one die from which a fluid is ejected and at least one nanowell at which the at least one nozzle ejects an amount of fluid. A method of dispensing a fluid, in an example, includes addressing at least one nanowell with at least one nozzle of at least one die, and depositing a fluid in the nanowell with the at least one nozzle.
