For a medical application, there is a need to be able to extract liquid (medication or other) from a vial (non-collapsible glass recipient with rubber septum) in a broad range of orientations, preferably all orientations. As liquid is removed from a vial, air replaced the extracted volume. As gravity pulls the liquid downwards, this might result in the extraction of air, which is not desirable.

We are looking for technologies which are able to extract liquid from a non-collapsible recipient, which are not affected by the orientation of the recipient. This can be either 1. guaranteeing that liquid (no air) is always extracted 2. separating air from the liquid, in case air would be extracted 3. detecting that air has been extracted, in case air would be extracted The first solution is the preferred route.
