  • Patent number: 11278888
    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.

  • Publication number: 20210165007
    Abstract: In one example in accordance with the present disclosure, a fluidic die is described. The fluidic die includes a plurality of ejection subassemblies. Each ejection subassembly includes an ejection chamber to hold a volume of fluid and an opening through which the volume of fluid is ejected via a fluid actuator. A pitch of the ejection subassemblies aligns with a spatial arrangement of nanowells in an array of nanowells on a substrate.

  • Publication number: 20200326317
    Abstract: In one example in accordance with the present disclosure, a fluidic ejection system is described. The fluidic ejection system includes a frame to retain a number of fluidic ejection devices. The frame has a form factor to match a titration plate. The fluidic ejection system also includes the number of fluidic ejection devices disposed on the frame. Each fluidic ejection device includes a reservoir disposed on a first side of the frame and a fluidic ejection die disposed on an opposite side of the frame. Each fluidic ejection die includes an array of nozzles, with each nozzle including an ejection chamber, an opening, and a fluid actuator disposed within the ejection chamber.

  • Publication number: 20200298226
    Abstract: In one example in accordance with the present disclosure, a fluid ejection die is described. The fluid ejection die includes a fluid feed slot to deliver fluid from a reservoir to an array of nozzles. Each nozzle of the array includes an ejection chamber, an opening, a fluid actuator disposed within the ejection chamber, and a fluid channel between the fluid feed slot and the ejection chamber. The fluid ejection die also includes a fluid cleaning structure to allow live cells in the fluid to pass to the nozzle while capturing other components.

  • Publication number: 20200116546
    Abstract: In example implementations, a method is provided. The method may be executed by a processor of a fluid dispensing apparatus. The method includes storing a correction factor for an unqualified fluid. A request to dispense the unqualified fluid is received. A dispense parameter is adjusted in accordance with the correction factor. Then, the unqualified fluid is dispensed in accordance with the dispense parameter that is adjusted.

  • Patent number: 9427734
    Abstract: The present invention is embodied in a method for precisely dispensing fluid, including treating an orifice of a fluid dispensing apparatus during a fabrication process by applying a low surface energy material layer onto the orifice, adjusting a thickness of the low surface energy material coating to a predetermined threshold and limiting backpressure of a low dead volume fluid delivery system coupled to the orifice to reduce interference or interruptions for precisely dispensing the fluid.
