Containment units are powered stasis tanks present in the Xenoresearch Labs on Eastern SkyTown, Elysia. They were used by the Space Pirates to study Phazon Metroids, and kept several of them captive. The units are powered by Energy Cell ID: GC-9713N-5 further into the Labs. Samus finds the Seeker Missile Launcher in a containment unit next to the Energy Cell, which she must remove in order to disengage the shield and obtain the Launcher. However, this also releases the Phazon Metroids. On her way out of the Labs, Samus will encounter many shattered tanks that formerly held Metroids, as well as intact ones which were empty. With the shield down, all containment units that are still intact can be destroyed with Ice Missiles or charged Plasma Beam shots. One containment unit in Xenoresearch A Lift contains an Energy Tank, which can be obtained after the Energy Cell has been removed.
