The invention generally relates to assemblies for displacing droplets from a vessel that facilitate the collection and transfer of the droplets while minimizing sample loss. In certain aspects, the assembly includes at least one droplet formation module, in which the module is configured to form droplets surrounded by an immiscible fluid. The assembly also includes at least one chamber including an outlet, in which the chamber is configured to receive droplets and an immiscible fluid, and in which the outlet is configured to receive substantially only droplets. The assembly further includes a channel, configured such that the droplet formation module and the chamber are in fluid communication with each other via the channel. In other aspects, the assembly includes a plurality of hollow members, in which the hollow members are channels and in which the members are configured to interact with a vessel. The plurality of hollow members includes a first member configured to expel a fluid immiscible with droplets in the vessel and a second member configured to substantially only droplets from the vessel. The assembly also includes a main channel, in which the second member is in fluid communication with the main channel. The assembly also includes at least one analysis module connected to the main channel.
1. An assembly, the assembly comprising: a microchannel in a horizontal plane;at least one droplet formation module comprising a sample inlet, an immiscible fluid inlet, and a junction, wherein the junction is located between the sample inlet and the microchannel and the droplet formation module is
1. An assembly, the assembly comprising: a microchannel in a horizontal plane;at least one droplet formation module comprising a sample inlet, an immiscible fluid inlet, and a junction, wherein the junction is located between the sample inlet and the microchannel and the droplet formation module is configured to produce droplets comprising the sample surrounded by the immiscible fluid; andat least one downstream separation chamber comprising a droplet receiving chamber inlet and at least one droplet receiving outlet, wherein the separation chamber is upright to the microchannel and out of the horizontal plane;wherein the droplet formation module and the separation chamber are in fluid communication with each other via the microchannel; and wherein the separation chamber has a wider cross-section than the microchannel cross-section to accumulate a plurality of droplets comprising the sample and is of a volume sufficient to separate the plurality of droplets comprising the sample from the immiscible fluid within the separation chamber. 2. The assembly of claim 1, wherein an aqueous fluid from the sample inlet is segmented with an immiscible fluid from the immiscible fluid inlet at the junction. 3. The assembly of claim 1, wherein the at least one droplet receiving outlet is located on the lower portion of the separation chamber. 4. The assembly of claim 1, wherein the at least one droplet receiving outlet is located on the upper portion of the separation chamber. 5. The assembly of claim 4, wherein the droplet receiving outlet is connected to a proximal end of a slide, wherein the proximal end of the slide is higher than the distal end. 6. The assembly of claim 5, further comprising an output nozzle in fluid communication with the distal end of the slide. 7. The assembly of claim 1, wherein the droplet receiving outlet is coupled to a vessel. 8. The assembly of claim 7, wherein the droplet receiving outlet is sealably coupled to a vessel. 9. The assembly of claim 7, wherein the vessel is a PCR tube or a test tube. 10. The assembly of claim 1, wherein the droplet receiving outlet receives substantially one or more droplets. 11. The assembly of claim 1 further comprising a reagent inlet, wherein the reagent inlet is in fluid communication with the junction or the microchannel. 12. The assembly of claim 11, wherein the reagent inlet introduces one or more amplification reagents to the junction or the microchannel. 13. The assembly of claim 12, wherein the one or more amplification reagents are for a polymerase chain reaction. 14. The assembly of claim 11, further comprising a coalescence module located between the droplet formation module and the separation chamber. 15. The assembly of claim 14, wherein the coalescence module is within or coincident with at least a portion of the microchannel. 16. The assembly of claim 14, wherein a sample droplet is merged with a reagent droplet in the coalescence module. 17. The assembly of claim 14, wherein a reagent fluid stream is introduced to a sample droplet. 18. The assembly of claim 14, wherein the coalescence module comprises an apparatus to generate an electric force. 19. The assembly of claim 1, further comprising a sorting module to direct the flow of droplets, wherein the sorting module is located between the droplet formation module and the separation chamber. 20. The assembly of claim 19, wherein the sorting module comprises an apparatus to generate an electric force.
