U.S. Patent and Trademark Office has released the abstract. According to the abstract, "A flow cytometry or cell sorting system includes a fluidics system and a flow cell. Under pressure, the fluidics system causes sheath and sample biological fluids to flow. The fluidics system can include a gas bubble to remove and eliminate gas bubbles in the sheath fluid; The flow cell communicates with the fluidics system to receive the sheath fluid, wherein a sample biological fluid flows with cells or particles through the flow cell to be surrounded by the sheath fluid; a deflection chamber under the flow cell to receive the drops of sample biological fluid and sheath fluid out of the flow cell, the deflection chamber to selectively deflect one or more of the drops along one or more deflection paths; and a droplet deposition unit (DDU) system in communication with the deflection chamber to receive selectively deflected drops in the stream of the sample biological fluid with the one or more biological cells or particles into one or more containers. A flow cytometer or cell sorter system includes a fluidics system and a flow cell. The fluidics system is under pressure to cause a sheath fluid and a sample fluid to flow, the fluidics system including a gas bubble remover eliminating gas bubbles in the sheath fluid; a flow cell coupled in communication with the fluidics system to receive the sheath fluid, wherein a sample fluid flows with cells or particles through the flow cell to be surrounded by the sheath fluid. The flow cell includes a drop drive assembly, a flow cell body, and a cuvette coupled together. The drop drive assembly includes a sample injection tube (SIT) in communication with the fluidics system to receive sample fluid. The flow cell body receives the sample fluid from the sample injection tube and sheath fluid. The flow cell body has a charging port to charge the droplets, the flow cell body having a funnel portion to form a fluid stream of the sample fluid surrounded by the sheath fluid out of an opening; and a cuvette coupled to a base of the flow cell body, the cuvette having a channel to receive the fluid stream of the sample fluid...
