Containment cell
A containment cell was a transparent cell used to contain medical hazards.

There were multiple containment cells on Cold Station 12. In one of them, the deputy director of the station was infected with Symbalene blood burn and killed by Malik and Arik Soong. Phlox was later placed in the same containment cell but was soon released. ()
