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: An apparatus includes a media that includes an encoded pattern to indicate a location of each of a plurality of dispensing locations on a receiving area for a pipette dispenser. The encoded pattern is employed to guide the pipette dispenser to dispense a volume to a selected dispensing location from the plurality of dispensing locations based on a predetermined dispensing location on the receiving area.

Abstract: A microplate lid is disclosed. An electronics board includes a plurality of board throughholes corresponding to well locations of a microplate. A cover plate includes a plurality of plate throughholes corresponding to respective board throughholes to define a plurality of plate-board throughhole pairs. The cover plate is located atop the electronics board. A plurality of directing lumens is at least partially defined by the cover plate. Each directing lumen corresponds to a respective plate throughhole. A plurality of user-perceptible array indicators is provided to the electronics board. Each array indicator is associated with a different plate-board throughhole pair than every other array indicator.

Abstract: An apparatus includes a microfluidic passage, a chamber, an inlet connecting the microfluidic passage to the chamber, a sensor proximate the inlet to sense fluid within the inlet, a first nozzle, a first fluid driver to move fluid through the first nozzle to draw fluid across the inlet, a second nozzle, a second fluid driver to move fluid through the second nozzle to draw fluid across the inlet and a controller. The controller sequentially actuates the first fluid driver and the second fluid driver.

Abstract: According to an example, a microfluidic apparatus may include a fluid slot and a foyer that is in fluid communication with the fluid slot via a channel having a relatively smaller width than the foyer. The microfluidic apparatus may also include an electrical sensor to measure a change in an electrical field caused by a particle of interest in a fluid passing through the channel from the fluid slot to the foyer, an actuator to apply pressure onto fluid contained in the foyer, and a controller to receive the measured change in the electrical field from the electrical sensor, determine, from the received change in the electrical field, an electrical signature of the particle of interest, and control the actuator to control movement of the particle of interest based upon the determined electrical signature of the particle of interest.

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: 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 channel, a foyer, in which the foyer is in fluid communication with the channel and in which the channel has a smaller width than the foyer, a sensor to sense a property of 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 determine whether the sensed property of the fluid meets a predetermined condition and to perform a predefined action in response to the sensed property of the fluid meeting the predetermined condition.
