1. A transfer device for transferring a liquid from a first vial to a second vial, comprising:
a resilient dome portion configured to create an air flow when activated by compression and re-expansion; and
a support body tightly supporting said dome portion to form a chamber comprising air for the air flow,
wherein the support body comprises a first vial seat, a second vial seat and a transfer conduit,
wherein the first vial seat of the support body is arranged to receive the first vial,
wherein the second vial seat of the support body is arranged to receive the second vial, and
wherein, when the first vial is received in the first vial seat and the second vial is received in the second vial seat,
the transfer conduit is arranged to establish a fluid connection between the first vial and the second vial, and
on activation of the dome portion, air is delivered into the first vial by the air flow, 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, and wherein the transfer device is configured so that
activation of the dome portion by compression of the dome portion causes air to be delivered into the first vial by the air flow, and
activation of the dome portion by re-expansion of the dome portion causes the liquid to be drawn from the first vial and to be delivered through the transfer conduit to the second vial.
