  • Publication number: 20220389499
    Abstract: A method for forming discrete volumes of aqueous fluid may comprise flowing aqueous fluid into a first conduit from a supply of aqueous fluid and flowing into the first conduit a spacing liquid supplied from a second conduit, the spacing liquid being immiscible with the aqueous fluid. The flowing of the aqueous fluid and the spacing liquid into the first conduit forms discrete volumes of the aqueous fluid, with consecutive discrete volumes of the aqueous fluid separated by the spacing liquid. The method may further comprise transferring the discrete volumes of the aqueous fluid and spacing liquid from the first conduit to a third conduit for processing.

  • Patent number: 11319585
    Abstract: A system may include a first conduit configured to form a first batch of discrete volumes of aqueous fluid separated by spacing liquid disposed between consecutive volumes of aqueous fluid, the spacing liquid being immiscible with the aqueous fluid volumes; a second conduit, fluidically coupled to the first conduit, the second conduit configured to statically hold the first batch of discrete volumes of aqueous fluid; and a third conduit configured to receive the first batch of discrete volumes of aqueous fluid from the second conduit. The third conduit can be configured to transfer the discrete volumes of aqueous fluid of the first batch for downstream processing.

  • Patent number: 10450604
    Abstract: A method for generating, within a conduit, discrete volumes of one or more fluids that are immiscible with a second fluid. The discrete volumes can be used for biochemical or molecular biology procedures involving small volumes, for example, microliter-sized volumes, nanoliter-sized volumes, or smaller. The discrete volumes are separated from one another by a liquid that is immiscible with the fluid(s) of the discrete volumes, for example, aqueous immiscible-fluid-discrete volumes separated by an oil.
