If you could create an apparatus that would allow oxygen to be introduced from the bottom of a container filled with water, and allowed the oxygen to displace the water, pushing the water out of a valve of some sort at the bottom, you would prevent any air from mixing with the oxygen (picture an upside down flask). It would take some engineering, but the theory is sound.
In a chemical plant it would be a blend tank or reactor. In a laboratory it would be a reaction flask or beaker
A flask is a container for liquids. It is similar to a bottle.

you hold the flask by its norrow neck to move it
