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 method of detecting passage of a particle into a target location includes receiving a sample on a die including a microfluidic chamber, the microfluidic chamber including a microfluidic path coupling a reservoir to a foyer, and moving the sample from the reservoir to the foyer by firing a nozzle fluidically coupled to the foyer. The method further includes detecting passage of a particle of the sample from the reservoir to the foyer via a first sensor disposed within the microfluidic path, and detecting passage of the particle into the target location via a second sensor disposed between the first sensor and the nozzle. The method includes recording in a dispense map, an indication of whether the target location includes a single particle or multiple particles based on signals measured by the first sensor and the second sensor.

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.
