  • Publication number: 20240067912
    Abstract: A flow electrotransfection device with a chamber for fluid to flow though, a liquid inlet channel for communicating with the chamber and a liquid outlet channel for communicating with the chamber, includes an electrode module for applying an electric field to fluid in the chamber, and further includes a fluid guiding structure for making flow velocities of fluid flowing through the central zone and the peripheral zone of the chamber tend to be consistent. The present disclosure solves the technical problem of relatively uneven the flow velocities of fluid at different zones in the flow electrotransfection chamber, improves the accuracy of the number of electric shock when the fluid flows though the chamber, thus improving the electrotransfection efficiency, and reduces the cell damage and even death from excessive times of electric shock, thereby improving cell viability.

  • Publication number: 20230285987
    Abstract: An enclosed centrifugation device is provided, including an integrated tube body that includes an upper part, a middle part, and a lower part, wherein the upper part is configured to have multiple openings each having an open state and a closed state. The openings that are used for sealed connection to external tubing, include the first opening serving as a liquid inlet and the second opening serving as a liquid outlet. Also provided is a method for segregating cells. The enclosed centrifugation device provided by the present invention can centrifuge cell suspension and realize rapid inlet, outlet, or replacement of liquid in an enclosed setting, which greatly reduces the risk of being contaminated for biological sample, and simultaneously meets the requirement by regulations that sample treatment by Class III medical devices must be fully enclosed.

  • Patent number: 10787764
    Abstract: A clothing ejection net for a washer or dryer and method of ejecting clothing from a washer or dryer. The clothing ejection net comprises a net body that reconfigures between a retracted net configuration and an extended net configuration in relation to the interior of a metal drum of a washer or dryer. Magnets on the sidewalls of the net body magnetically attach the net body to the interior surface of the metal drum during washing and drying operations. A pull cord at the front face of the net body pulls the net body out of metal drum, to an extended net configuration. Magnets on the inner surface of the net sidewalls separate from magnets on the outside surface of the net body, creating a discrete snap separation to the extended net configuration. The extension of the net body ejects the clothing from the clothing retention cavity of net body.
