Abstract: A device for providing a droplet of a liquid stored in an interior of a vial is disclosed that includes a support body and a resilient dome portion mounted to the support body to form a chamber having air, with the dome portion being configured to create an air flow when activated by compression. The support body includes a vial seat, a nozzle, and air flow and transfer conduits. The support body is arranged, when the vial is received by the vial seat, such that the air flow conduit establishes an air connection between the vial interior and the chamber, the transfer conduit establishes a fluid connection between the vial and the nozzle, and, upon activation of the dome portion, the air flow delivers air into the vial that causes liquid to be transferred from the vial to the nozzle through the transfer conduit.

Abstract: A device for transferring a liquid from a first vial to a second vial is disclosed having a dome portion configured to create an air flow when activated by compression and re-expansion, and a support body tightly supporting the dome portion to form a chamber with air therein. The support body includes first and second vial seats, and a transfer conduit. The first and second vial seats are arranged to receive the first and second vials. When the first and second vials are received in the first and second vial seats, the transfer conduit is arranged to establish a fluid connection between the first vial and the second vial. Upon activation of the dome portion, air is delivered into the first vial, thereby creating a pressure rise in the first vial which causes the liquid to transfer from the first vial to the second vial through the transfer conduit.
